Another reason no-one has mentioned is so she can scope out the car(s) you drive. Hence you get that park in the local car park and call me bollocks. I think they hold off the address, as mentioned they can be shagging another punter, not ready on time because they've got no sense of time management, not actually an escort - a PG\webcam scam. A postcode is the minimum I leave with, no turn left at the red house style directions. Goose chases, just say no.
