Kind of puzzling ... even we forget to pay, i am sure the girl won't ever forget to collect.
When all dressed up and ready to go, if you make no move to reach for your wallet, you think she won't prompt you?
Some girls also too trusting, can go and shower on their own after the deed, leaving the customer to just scoot off freely.
What to do - in this kind of biz, go in with eyes open, and don't expect to meet nice guys and nice girls right?
