Was in back dance area of club and saw these things, 1) the toe sucker. And we are talking dancer toes fresh from the shoe. 2) the guy who just wanted to have the girl kick his crotch with her heal. 3) the guy getting a good grind basically yelling out "hoo. Hoo, hoo". Try concentrating on your dance with that going on.
I am not judging, but...
In SF I saw a guy with a backpack and he had an arsenal of dildos and inserty thingys.
Oh and he would grunt and make sex sounds when using them. This I didn’t actually see. He was in the booth next to me.
We heard a dancer in a neighboring stall say, "Do you want me to pretend I'm dead?". We looked at each other like WTH?
I saw a guy who would pay for dances which were done on couches. This guy instead would lay flat on his back on the floor and have a woman standing on his chest and stomach. The dj/bouncer looked over at me with this confused look on his face shaking his head.
My former ATF and other strippers have shared stories with me, and kicking a PL in the nuts is not an uncommon request. Other variations of this have been to get kneed in the balls or have them stepped on with her high heel - and specifically the literal heel. Getting pegged was also not too uncommon but this was a OTC thing and not done in the back room.
(And I'm glad I never had to witness any of this.)
In the VIP room, the stripper told me the box of Kleenex tissues on the table can "come in handy" during a dance.
Step on their balls. Periodically say "yes papi" while the customer delivers a monologue in a language she understands vaguely at best.
If you can think of it, some stripper somewhere has gotten that request. Rule 34 applies to strip clubs too.
Ok, one more. My ATF had a Wolf of Wall Street pulled on her. Guy took out the white powder and took it off her ass.
A guy who had a special outfit for VIP. He would buy a room and pay 100 for every girl who would come in and piss on him. I went in afterwards one time and the room smelled like it.
