There are some situations where all sales are final.

A 50-year-old woman named Pamela Landry is a PROSTITUTE in Baton Rouge, Louisiana.  And she went to a motel on Sunday morning to meet a 61-year-old client named Michael Pratt.

He'd agreed to pay her with money AND crack . . . but after they finished up, he was furious and demanded a REFUND because she didn't provide, quote, "services."

He wouldn't let her leave the motel room, so she called the cops.

He was arrested for prostitution . . . and she was arrested for prostitution and possession of drug paraphernalia. 

(Here are their mugshots.)
