How do figure I am being hostile? Toward whom?You realize that's why we have these discussions, right? To clue others in? No need to be so hostile.
Getting "taken" by taxi drivers on Cozumel is at worst a minor inconvenience, and it is easily averted by using one of the several remedies we have discussed in this thread and others. I'm not going to waste precious vacation time agonizing over it, whether it happens to me or anyone else. If someone were to lose their cool and get into an altercation over it I am not going to have a lot of sympathy for them; people who react that way aren't worried about the money, they are just pissed because they lost the game.
Don't get mad, just learn how to play better.
