A bartender who covers someone’s bar shift one time at a random bar or restaurant. Preferably in Washington, DC.
George: Doesn’t that guy work at another bar that we were just at?
Robert: Yes, he randomly works all over the place. That’s a Halligan. Yo Halligan, we need some shots and beers down here!
