I think this assumes people are more respectful to their own, at least overtly, than to guests, but this is an incomplete view. In cultures where hospitality is high, guests are treated with a hospitality and patience that is not extended to the locals. Furthermore, foreigners are more likely to be viewed as people unfamiliar with the conventions and customs of the region, and therefore some reasonable patience is shown, whereas locals are expected to be on top of such things.
What insane people get isn't dignity and true respect, but avoidance!
