Like from what I understand you're not allowed to touch the workers because then it becomes prostitution. So like. A bunch of boys just get together and sit down to watch some girls dancing naked? And they just kinda grin at each other and say "hey isn't it awesome when there's boobs?"
You can't jerk off so they just go to get boners with their buddies? You can do that at home. You can just watch porn with the fellas or have a circlejerk.
I've never understood why it's seen as a straight masculine thing to go to a place where the only thing you can do is get horny with other men.
Yep. It's a safe(r) space to negotiate offsite sex work. The club aggressively filters out the the most obvious perverts who get handsy at the mere sight of a boobie. Not to say you can't make good money just dancing, of course—there's plenty of white boy incels who are too scared to break the law, and throw away a fortune trying to make a dancer their girlfriend because she was nice to them. But the girls who made bank were always doing side work.
That's why you get the lasagna, or go to the mob front pizza places. They load up that pie with absurd amounts of cheese because they have no concept of what is and isn't profitable. A pound of cheese can make any mid recipe quite palatable!
