My first exposure to the Taxi Mafia was when several years ago someone brought 2 motorcycle-tricycle type things (are they called Tuk Tuk's?) where the driver sits up front and there is room for 2 passengers on a rear seat to provide an alternative transport to tourists. Legend is they were rolled off a dock into the sea within 2 hours of coming off the ferry. This story may, or may not, be true...but I believe it.
If someone chooses to avoid Cozumel because of the unwritten rules of the Taxi mafia, a 16% tax that they weren't told and didn't ask about when booking their dives, medical care that may not be up to American standards (or expense), dive boats without a permit, an entire family of five and a dog riding on one scooter...with no helmets, bait and switch tequila stores, crappy jewelry sales, or the inevitable Gringo Tax, so be it. They wont be missed. It merely increases the likelihood that my favorite post-dive table at The Thirsty Cougar will be available and maybe I will buy
@ggunn a Negra Leon while I enthusiastically enjoy my beloved Bohemia Obscura and poblano pollo burrito.
It goes without saying that these negative experiences are the exception to the rule. For better or worse, Cozumel has grown to be what it is based on millions of very happy tourists, many return every year for the people, the diving, the beer, the food, the inexpensive vacation cost, the ease to get to, the world class diving, the beer, the sight of the Cozumel Mini Van, the beer, the diving, and to pay respects to Lola, the former Canine Mayor of Cozumel. (she hated me...but loved my wife!)
Safe travels to all, wherever you may roam.
