Worst, union crew at Beacon Theater, I was bass player at a concert there, the place was absolutely insane for the guy I was playing with (Miguel Mateos - latin rock guy) and when we ran ofstage at the end of the show, the crowd was going BONKERS for an encore, and the crew literally slammed the door shut in front of us and demanded a shitload of money to even do one more song.
We couldn't get back out to the stage until they had cleared the building, it almost caused a riot, I've never seen such an incredible pile of wet assholes before or since.
