I still don't see it's"wrong". Again, it's a business decision by transferring the risk of efficiency lost to customer to maintain their focus on customer that trust them. When the girls come out, they have to put down their phones, takeoff robes, put the high heels on, tidy up their hairs a bit etc. Remember many girls do over 12 hour shift. It can be exhausting.
I personally never got charged before line up. I only see lineup about one out of 4 visits. Other times I book either a regular or a recommendation from the forum. They always let me pay after lineup.and so far, I haven't walked away a single time. In fact, there are more gorgeous girls than I can catch up with.
There was only once the reception asked me how long I want to stay, I said half an hour, it was late and I have work next day didn't want to stay long. There was no other punters there only me at the time. The reception hesitated and asked me which type of girl I want. Instantly I can sense he didn't want to pull a line up just for me. Which is fine. Then I described to him what I typically like. He recommended a girl which I went for. It was a very good punt absolutely no regrets. In fact, this girl became my regular for a while.
