I feel, that we as tourist should assimilate when we travel, not bother.
But how do you teach that, when at home many do not teach it.
I don't know...i've always put myself in visitor mode and act accordingly when i go to a new place.
But some folks don't even know how to act like good visitors or guests.
It is sad indeed. And it is hard to find a balance with preserving and the temptation of tourism money.
