End result was ALL her punters had to pay her new price
I can even give you an extreme example from my experience where overpaying has ruined the market in a whole neighbourhood and to an extent a whole city.
Rio used to be a prime punting destination. Then a lot of rich pussy-starved Americans started tipping heavily. It's what Americans do. Pretty soon the prossies got wise. It's not that they like those Americans. The American tourists tended to be loud, vulgar, and totally ignorant and oblivious of local customs, manners and prices. Pretty soon the prostitutes started targeting Americans. You could also have witnessed the change on the ISG board. It turned from 'how to get good cheap pussy' to the rantings of Americans that paid stupid money.
It used to be possible and relatively simple to get an 'arrangement' with an attractive young woman for several days of companionship and unlimited sex and at a pretty negligible cost. It was still good money to her and better than what she'd be doing otherwise. It's still not impossible, but much much harder unless you pay silly money. Plus the service will be that of a 'professional' (i.e. Professional money extractor) rather than 'gfe'. The Rio SPs were (and in a way still are) the most savvy SPs in the world and of course American overpaying isn't the only factor in the downfall of the punting scene there (the World Cup and then the Olympics didn't help) but it is the main one.
If you overpay, people will charge more. In America, you will even get more customers by charging more (they simply equate price, unseen, with quality).
I agree with JRC on many things but overpaying prostitutes is simply wrong.
