I meant to ask this before but forgot. Once in a while when I pay by credit at Utopia, a girl tells me that the attendant has to pay a 10% service charge to the house. Some girls run the card without saying anything. Once Liv asked me if I wanted to pay the 10% for the girl. I don't get it - does management at Utopia charge the girls when the customers use visa or is this a play for tips? Can management even do that to the girls?
