If she handed the money back, that is the price she set for herself.
If she is young, it is probably true. She is thinking why should she get the same thing guys are paying 40 and 50 year old
Amp girls. She feels she is worth it and she is probably getting it. Again if she handed you the money back she clearly has a value in mind for herself, so she doesnt feel the need to be devalued by clients.
If you do not want to pay it, just move on to another girl.
Remember, they do not have to provide the service we want, nor do they have to provide it at the price we want, we are very fortunate when they do.
