I think you focused too much on the "price" of Dolly rather than her "value"(Oscar Wilde) The different classes between the girls have never been differentiated by types of services no where on this forum or Ginzas website has that been said.

I mean if anyone can point me in the direction of a young Thai girl who does DFK and bbbj in Sydney CBD for a similar or less price per hour I'm there. I doubt anyone could though.
