Thanks for the detective work guys. I made the appt already - should I just go and see who it really is and make the decision then?
As you can all tell, I am new to this.
Personally speaking no you should not visit her. She or her pimp are using blatantly false advertising. No way should that be encouraged or rewarded. Even if you did I would predict a pisspoor experience.
You can meet really nice girls in that price range who don't lie in that way.
Especially as you are new find someone nice who'll treat you with respect.
