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

To me the taxi thing is the worst. There are official taxi rates which are not followed, the taxi union got together and made their own rate sheet. To be fair they have issued too many taxi licenses so there is not enough work to go around. I am friends with a taxi driver so this is coming from his side. I understand this is a bad situation for people that live here year round that do not want a car. Before I stopped using taxis I would tip only those that offer a reasonable rate. If you cannot find a reasonable you can always use a combi but that is difficult if you leaving the store with ice cream.

I tend to tip more at lower prices local restaurants and the normal 20% at high end restaurants. Do not forget to tip your maid daily at a hotel and also checkout in an Airbnb. The baggers are not employees and only receive tips, $20 is fine, same for anyone helping on/off pangas. All of this is probably considered over tipping by many locals and causing inflation. My opinion is that it is kinda expected when living in a tourist destination. We are currently in Cabo, you should see the prices here.
