A few are sometimes miffed but most do not seem to mind. Over the past several years, the chicas have been in the habit of simply dividing by 10, no matter what the current fluctuations in the exchange rate. This was true even when the dollar dipped below 10 for a few periods. Then, it was better to pay in dollars, not pesos. But the chicas did not seem to mind, either way. On the other hand, I have noticed that most escorts want to be paid in dollars. I am not sure what the reasons are for this but one theory might be that they are just better informed about the in's and out's of currency exchange rates than the la Zona chicas. Sampson might have a better explanation for this.
