Plenty of people are taking a stance based on "values" and "integrity." I would not doubt that plenty of taxi drivers are saying the same thing about you. There are many countries around the world where the more money you have the more you pay. Even for locals. I have met plenty of people in foreign countries who would go to their local market on a bicycle rather than their scooter because they would get charged less that way.
Integrity might be very differently expressed by different people around the world. To think that your version is the only version or the only correct version is rather myopic. A taxi driver who drives a tourist who has enough money to travel and buy expensive dive equipment get into an argument over a few pennies or even a few dollars might just look at that person as lacking integrity, as well.
