I thought this might be a Junkman story but I could not verify it ... 
---------------------------------------------
A man, new in town, goes to the best brothel in the city. Choosing the best looking girl in the place, he retires to a large and well-appointed suite, where he has some of the best sex of his life. Satiated, the man asks the madam, "How much do I owe you?"
The madam motions for him to put away his money. She then pulls two hundred dollars out of a purse and gives it to him. She fends off all his attempts for an explanation.
Naturally, the man returns the following evening. He gets the same treatment, and is again given two hundred dollars.
The third night he does the same thing, but when he sees the madam she asks him for three hundred dollars.
"Wait a minute," he says. "The first night you gave me two hundred dollars. The second night you gave two hundred dollars. Now you want me to pay you three hundred? Why?"
The madam smiles and says, "Tonight you weren't being filmed."
