I think this issue has been raised a few times but I don't think there was never a general consensus. Ok, so you book through a reputable agency (not craiglist), you get there and she's not ugly but she doesn't do it for you, should you stay? Would leaving cause the agency to put you on a black list? Or create "badwill?" Is leaving the "ultimate" insult for a SP? And if you do leave, should you give the SP any money (i.e. a termination fee)? I would appreciate it if some SPs and agencies would respond to this. Thanks.
