Last one I saw, a group of really big guys (5 guys or so, all over 6'2", all over 250, I'd guess) were getting drunker and louder and angrier, and when the manager asked them to leave they decided they needed to beat him up for that. The manager is gradually talking them out the door while yell louder and louder threats of increasing severity, not knowing the police were already waiting outside. Best part is, as he's passing my table, and the large drunks are looking away, he asks the guy I'm playing against for his cue. The guy hands it to him, and he puts the tip against the carpet and steps on it and put the broken-off butt behind his back to use as a club in case things turn ugly on the way out the door. Luckily the guy was playing with a house cue. I'm glad he didn't ask for mine!
