9-5 gilrs are definitely available
Well, I haven't test 9-5, but I do know that many girls preferred to work "normal business hours". The most obvious reason is that they don't want their parents to know that they are in "special business", so they told their parents that they work in "pure message parlors" with normal business hours.
I have an unproven theory, with message parlors the better looking and younger girls are the day shift and not the night shift. Because if a girl can work night shift, and offers FS, she can make 5 times more money in "jio-dian" then in massage parlors.
This is why if I want afternoon quickie, I go to massage parlors (I will try SC soon), but if it's night and I need quality? I have to ante up my wallet.
