I think the circumstances "tourist haggling with vendor" and needs "tourist wants to experice other culture" where very well established. Whether or not I know anything about this, is an assumption that you are making without knowing anything about me.

Of course how and why and where money is spent is stock-full of morality and ethics. That's not an idea that I privately came up with myself.
