Yes, the younger the girl, the more picky she will be (usually). The younger girls only visit the spot on the weekends, but still, the girls really don't decline customers.
The girls here would love to get a 80-year-old man, cuz he's a easy customer to deal with.
I spoke to a girl that advertised on flushingicall, I told her to put in the title ,"foreigner is welcome".. I told him most girls don't see Americans, if she does that she'll have more guys she can deal with. She never did it though. I always thought it was strange how a girl would see a foreigner at a spa, but they won't do it when they're independent. Maybe they're just scared of the neighbors talking or something.
But making the girl pay the house fee, that's very logical! If she doesn't accept the customer, she's causing the house money.
