I've never experienced a line-up... personally, I find it degrading to the providers...but they could be so jaded after the time they've put in, and with so many different men, that it doesn't bother their egos (to not get picked). When I go to my current favorite
AMP, when the
mamasan greets me, I just ask for whoever is my current favorite provider, if she is there, fine, if not, I let the boss set me up with someone.
I went one evening, asked for my then-fave, and
mamasan says "I have new girl here, she get here 3 hours ago. I fix you up with her, she good looking, take good care of you."
She (the new provider) takes me to the
TS and when she comes back to the massage room, after returning from cleaning the shower room, she brings in my then-fave. My fave says she's going to help the newbie, but she won't get paid, the new girl will get it all for starting so late...about 2 hrs before quitting time.
This was only my second "4-hand" massage. Surprisingly, I lasted just as long as if it would have been a one-on-one session.
I guess that you just need to ask for who you want and maybe have a fall-back provider in mind if your first choice isn't on duty....or already working on someone else.
