Had you told the whole story the 1st time, my response would've been different. However I still don't feel like you can say any one group of people are all bad. The worst experience I had In Cozumel, was my fault. I ate some pickled tomatoes ( I thought)which turned out to be pickled habanero peppers and thought I was gonna die for a few secs,(not really, but it was intense) but it was my fault for being uniformed, so I can't blame them. I've always found the people to be very nice there. I honestly think everyone place in the world has imperfections and yeah there may be those who try to "steal" your money, but the majority of them make money from tourists, so I assume that's why they're always nice.
