Maybe it's not fake, the kid had to do something to really piss them off as that's the only time I've seen bouncers get hostile since they and the club can get easily sued if they look at someone the wrong way. Bouncers usually are cool and most of the time are lazy and never want to do anything other than flirt with the chicks.
Yeah, bouncers are usually fairly normal people, but the ones who're "out there" are VERY out there. Especially given that this is a gentleman's club, I could see this particularly bouncer easily being on a power trip while also--given the environment--thinking this sort of thing would go unreported. He probably filed the report in an attempt to cover his ass in case the person he attacked went to the police.
