Ive never been sad enough to have to visit a lap-dancing club or similar, but from what ive seen on tv cash is paid directly to girls from the punter and the club owners skim off at end of night, same with escort agencies, a lot used to launder money from organised crime so cover their trackslike the police who catch the dummies, I think the tax man would go for the easier option,those girls fishing for lots of feedback may regret the paper-trail!
