Maccadam's Old Oil House

Situated over at sub-level six on Cybertron's lower-east quadrant, or just east of the High Council Pavilions in Iacon, is one of Cybertron's most renowned enterprises: Maccadam's Old Oil House—the biggest single source of black market fuel on the entire planet. Its main attraction, beyond the excellent service, exceptionally pure oil and general selection of fuel, is that the proprietors make no distinction between Autobots, Neutralists and Decepticons. If you can pay, you can stay.
Fuelled by the bar's ability to keep the burden of war outside its doors (most of the time), rumours circulate that Maccadam's Old Oil House is no ordinary establishment. Rather, it would exist out of the normal space and time continuum, possibly even be a nexus for multiple dimensions, and its secretive owner Maccadam would be nothing less than one of the thirteen original Transformers. Of course, people tend to gush out a lot under the influence, so little attention is paid to this inevitable falsehood.

Answering a question about his plans if he were Decepticon leader, Dreadwind said that he'd take over Maccadam's Old Oil House and call it a day. Dread Tidings #276
The Wreckers liked to visit Maccadam's Old Oil House on their downtime. So when the members of the group were disheartened because they had to abandon Operation: Volcano, Twin Twist, Roadbuster and Whirl took their mood to the bar to drink it off. They were discussing their decision to step out of the mission when a loudmouthed Decepticon stomped into the establishment and immediately turned his attention to the bar's musician. Apparently having a history with the entertainer regarding discrepancies in their respective musical tastes, the Decepticon started beating him up for still playing "that aural atrocity". Twin Twist wanted to help, but Roadbuster declared it was not their fight. Twin Twist called slag on that, punched the Decepticon into a couple of pieces and speeched his colleagues that it always was their fight, inspiring them to resume participation in Operation Volcano. Target: 2006

When Thunderwing rose to power, he ended Maccadam's status as a neutral area, much to everyone but the Decepticons' annoyance. Quickswitch pondered bitterly about this while waiting impatiently for his Decepticon informants inside the bar. His attention was first erroneously piqued by the arrival of Dreadwind and Darkwing, who, feeling like losers, had chosen to drink away their sorrows at Maccadam's Old Oil House. Shortly after them entered another Decepticon, severely damaged, who warned the staff and customers that "creatures" outside had eaten his comrades and were coming this way. The bartender was unimpressed, stating that the bouncer Rocky would stop them. He wouldn't, as the Mecannibals had already eaten him after having followed the Decepticon Powermaster duo to the bar. Making their entrance, the Mecannibals immediately began tearing up the joint, with the pair of inebriated Powermasters blissfully unaware of the chaos around them. Quickswitch decided he couldn't just stand by and watch the slaughter, so he leapt into action. After a brief skirmish, Quickswitch used his tunneling mode to destroy the bar's supports and bury the Mecannibals alive deep underground. Finally making contact with the present again, Dreadwind and Darkwing noticed they were alone in the wrecked bar and decided to split before anyone would blame them. Out to Lunch!
Classics
During the time Cybertron was run by the Mini-Cons in preparation for the return of the bulks, Maccadam's Old Oil House was of special significance to the population. It had always been a place of peace, but to the new breed of Transformers it served as a testament to how their species could find joy and harmony even in the worst of times. Also, due to its immunity to the ravaging influence of the war, the place was in working order —excluding the entrance sign that notoriously refused to stay properly lit— and stocked when the Mini-Cons came upon it. It was soon reopened to serve as a place for relaxation after a long day of rebuilding Cybertron and killing Mutants.
The Dinobots and Broadside visited the bar one time, the former merely to unwind, the latter to attend a secret meeting about the progress of his plot to claim Cybertron for the Mini-Cons permanently. For his next move, he intended to have Modus Prime murdered and blame it on the bulks, a radical turn of events he'd need time for to convince his allies. As one of the waiters in on the conspiracy arranged a private room in the back area for them to talk, Broadside met up with Sledge and Wideload. With the crowd thin that night, the Dinobot Knockdown, seated at the other side of the room, had a clear view on their activities, but didn't think any of it.
Once Broadside and company had left for the back-room area, Knockdown forgot about them until he heard angered shouting coming from the direction they had gone to. The Dinobots functioned as Maccadam's Old Oil House's unofficial bouncers if they were around, so Knockdown felt obliged to check on the situation himself. He was right in front of the door to the meeting room when the waiter came back out in a rather suspicious manner, allowing Knockdown only a faint glimpse of what was going on inside. The waiter was startled when he spotted Knockdown and came close to killing him in panic, but managed to regain his composure before doing anything that gave away his malintent. The waiter apologized for his behaviour and went on to distract Knockdown from the scene by noting how grateful the staff at Maccadam's was for the Dinobots' occasional help and offering a bottle of Siebenaler Vintage if the Dinobot would give him some tips on handling bad customers.

Maccadam's New Oil House opened in Rodion shortly before the Clampdown. Megatron, Impactor, and Rung were patrons. Chaos Theory #1 Nightbeat and Quark were standing outside the bar when they discovered a body hanging from the nearby Interstate Bridge. Post Hoc Windcharger, Huffer and Brawn were seated there when they caught a broadcast from Optimus Prime asking all Cybertronians to join him against the Decepticons. Broadcast Hot Rod was drinking at Maccadam's shortly after graduating from Autobot Academy, and ran into his old friend Slinger outside. Primacy #1
In the early stages of his leadership of the Autobots, Optimus Prime felt that his abilities to hold a speech were on par with someone who had had too much to drink at Maccadam's. The Iron Age
Once the war was over, Blurr decided to re-open Maccadam's Old Oil House in the shanty town that Iacon had become, intending it to be a place where Autobots, Decepticons and NAILs could all relax without the usual tension. A Better Tomorrow The bar proved popular, and Jazz and Sky-Byte formed a musical/poetic duo there to entertain the patrons. Interference Patterns Later, Bumblebee visited the bar to enlist Blurr's help in locating the missing Ironhide. Night and the City
With Megatron's return and the ensuing Decepticon riot, Blurr battened down the hatches at Maccadam's and sheltered several NAILs (plus a couple of disaffected Decepticons) there. City on Fire With a rampaging mob outside, Arcee appeared inside the bar and tasked Blurr with transporting two more Decepticons—Dirge and Swindle—to Bumblebee. The rioters then set fire to the bar, forcing the remaining occupants to abandon it. The Verge Following the defeat of the Decepticons, Blurr returned to rebuild Maccadam's and kicked out new NAIL leader Starscream, who was looking to use the bar to connect with his people. Three Monologues
After Iacon was abandoned in the wake of the Dark Cybertron disaster, Blurr moved Maccadam's Old Oil House to city mode Metroplex, where it continued to be a popular watering hole. A 'Bot and Her City Circuit and Longtooth attempted to interview the patrons on a recent explosion in the Acrolight District, only to be thrown out by an annoyed Blurr. The brief words the reporters got out of Waspinator were of interest to Windblade and Chromia, who then visited to Maccadam's to interrogate him. Windblade #2

Given that Iacon was no longer in use post-Great Upgrade, it would seem that Maccadam had moved his establishment to Cybertropolis, as Rattrap offered to share a vat of vintage oil from Maccadam's with Trailbreaker when he and his comrades returned to Cybertron after the Great Reformatting.

A bartender was told by somebody to expect a group of four temporarily deceased Optimuses to arrive in one of the bar's backrooms. He provided a table with four chairs and pitchers of oil for their refreshment. Armada Optimus Prime was first and the bartender reminded him of the tab he has running. The three other Optimuses soon arrived to talk over the doubts Armada Optimus was having about his leadership. After that, the bartender returned to inform them they needed the room for other purposes they had to leave through the back door, which they did, returning to life. Prime Spark

Not all Transformers responded to the order of a planetwide evacuation. The Decepticons Crush Groove and Jackhammer didn't buy into the mass hysteria and remained on Cybertron, using the opportunity of a deserted world to break into Maccadam's Old Oil House and steal all the energon and oil they'd ever need. Though not the smartest crooks in the history of their race, they would likely have gotten away with it if not for the arrival of the Heralds of Unicron known as Ramjet and Nemesis Prime. Ramjet offered them a place among Unicron's minions, but the duo declined impolitely. They were subsequently killed. Crime just doesn't pay. Balancing Act

Notes
- The idea that Maccadam's Old Oil House exists within a dimensional nexus, allowing characters from different universes to crossover and interact within its walls, is a
shameless ripoffdirect homage to Munden's Bar from the comic book series Grimjack. Munden's existed within a dimensional nexus allowing characters such as those in Grimjack and other indie comic publications (including the Teenage Mutant Ninja Turtles) to meet up in back-up features.
