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

I am a part timer. I come for a few weeks a year. l would like to hear from a resident who understands the local economy.

l was once told that we shouldn't tip taxi drivers because locals don't , so the drivers will pass up local fares in favor of tourists.

In the US I tip in sit down restaurants , but not in grocery stores , fast food places , etc. I am not wealthy but I am pretty loose with my tips, especially with the staff at my hotel, but I hear that just creates an imbalance between those who have a job with face time with tourists and those who don't . I am not a miser nor a bleeding heart. I know all those smiling faces appreciate that I will be spending my money while in am Mexlco. So what is a fair tipping expectation there?
