I'm well aware of that but catching a guy with a girl in the car, does that mean he was kerb crawling, what actual evidence would the cops have unless they have something on you for requesting a service I think it would be hard to prosecute.
BTW - two escorts in a room is deemed to be a brothel, so a guy looking for a ffm 3sum could find himself in a spot of bother too.
Is it illegal to meet a male escort for sex?
