well, guys/chicks who work out don't go to these, because what's the point? they know supps are a scam, they know what's out there, and would rather stay at home.
what you're left with is guys who go there to make fun of others (blockhead/ed & crew) and sick schmoes who get off on seeing oiled up men walk around.
as for the guys who say "hey the chicks are hot"...well, ever been to a strip club? you see real pussy, not covered up, and while you may have to pay the 10 bucks to get in, at least you won't have to look at kamali.
