Christie's cabaret dance prices

In Phoenix Christie's has $10 dances. They used to have $10 dances in canton but now they are $20 like the rest of Christie's in Ohio. I read a recent review of the North Carolina Christie's and he said $30 for couch dance or $60 for a VIP dance. Any one know how Christie's sets their dance prices? Does corporate set them based off their market research or is it up to the local management?
