What he fails to mention is that following his advice could get you 5 years in prison
I have a friend who I bounced with a few times back that went all Kung Fu on a guy when the police couldn't restrain him (typical tough guy) and he came after my bud after we tossed him. Before you know it, my bud had him down with his ear damn near detached from his head. Blood everywhere.
Needless to say we both never bounced at this place again (got canned), and the guy filed a lawsuit against us and the owner.
