First of all, I appreciate the constructive input!
I see what you are saying, yet I don't see this as a good enough reason to behave like a jerk in other cultures and especially towards people (not tourists!) who have nothing to do with their 9to5 sadness. I don't have anything about tourists venting off energy, as long as this does not infringe on the dignity and privacy of those that the tourists are actually "visiting."
