Like fro said, they sound like they need other jobs. I understand your frustration bro, but bouncers have to back eachother. Regardless of what the first prick did to start shit, when a group of bouncers see a guy pounding the shit out of one of the others, they're going to jump on your ass in any club. They did handle it wrong though. Bouncing is all about controlling people and mellowing situations, not pounding them.
If a cop got out of line with your lady and you break his jaw, his buddies are going to be all over you in a flash regardless of what he did or said. Same bullshit thing
