I don't doubt he is a category of provider for a select group that many of us don't fall into. But how exactly does one get a receipt for payment from a sex worker for services rendered and the deposit for a promise of future services? Is one able to use them as a tax write off expense like entertaining clients or business travel?! I have heard of agencies discreetly charging credit cards, but I've only ever hired the type that only accept cash, though some have accepted foreign currency from me when their own is devaluated or if they travel abroad.
