I'm fairly care-free and don't stress even when people around me do. However, I can't agree with the "their country, their rules" type of responses, as if that makes this happened okay.
If the experience is terrible for any reason, it's reason enough to not go, or find another vacation spot. I'm not trying to impose my values on them, but rather The whole reason for going on vacation is to have a good experience. Why was the experience crap? Bad food, bad politicians, bad taxis, bad hotels, bad hospitals, riots, wars, etc? Other than the life-and-death reasons, it really doesn't matter why, just that it was crap.
