Fortunately everyone on this forum is allowed their opinion. I expressed mine based on an experience my wife and I had last Sunday. At least some of the posters here agree with me.
I have no axe to grind here, except that (and I repeat) what happened was a bad reflection on Belize.
In general Belizean people are friendly, honest and welcoming to their country. My feeling is that tourists need to be aware of prominent exceptions.
