Permanent residents

I sometimes do.

I book my flights online. To get the FMM fee reversed, I have to phone in and wait, and wait.

Then I have to explain the topic to someone who sometimes has no idea what I am talking about.

Then I have to convince them that I really am a permanent resident. Typically that involves taking a photo of my card and either emailing it to someone or uploading it to a link.

Then I have to monitor my credit card statements to make sure it really was reversed. And I might have to do it again.

Sometimes my time and hassle reduction is more valuable than my US$30(?) contribution to the Mexican economy.
