a friend of mine was dared by a couple girls we met one night to go in and see if they would do happy endings.
so he goes in, gets a blowjob or whatever, and when she left the room, he put his hand in her tip box and grabbed what he could and ran out with his pants around his knees. he ended up with around 80 bucks or something. poor girl sucks some guys dick and loses 80 bucks for it.
