Tips, what is the "right" way to do it's in Zihautanejo.

Taxi drivers if they do something extra but we almost never use a taxi. Baggers at the store, something, up to 20 pesos. Restaurants, sit down, 20%, taco restaurants, that kind of thing, 15 to 20%.

That is what we do and we live here. Not hard and fast, but in general.
