I've seen a few providers at our local Asian massage parlors, but they have advertised specifically.  Once, when I got there I was given a completely different provider, who wasn't bad but I'd already paid the $50 house fee, so what could I say?  Another time, the one I was supposed to see didn't seem at all like the advertised picture and looked like she'd just been woken up, so I chose another more comely (and ready) lass that was wandering about and ended up having a decent time. In my area, when the actual parlor advertises, they put up a variety of pictures of different race providers.  Am I to assume these girls are actually available, or am I supposed to just go there and ask for a parade of "options"?
