Dollars/Pesos and Fishing

Been reading a few threads on here about hotels charging in dollars and really sticking it to the Mexican and Canadian tourists with the strong dollar. What about the fishermen? They charge in dollars and I don't see one thing about them here. I have not come to Zihua for years but have been fishing in Cabo, they charge in dollars also and have not dropped their rates. I do plan on fishing with Ramon Olea later this year. His site shows $180 dollars per day. So if I pay in pesos, which I prefer as it is easy to get funds from ATM's for me, I should give him about a 15 to 1 exchange or I will be screwing the Mexican and Canadian tourists. So I should really only be paying Ramon $2,700 pesos instead of the current exchange rate that would work out to be $3,300 pesos. To be honest, there is no way I would give Ramon a lower exchange rate but just an observation. Then there's a 25% tip on top so that will really distroy the local economy. Guess I'd rather screw the tourists than a local, that's just the way us ugly Americans roll.
