Are you collecting "local" trophies? The quaint lives of indigenous grandmas and blue collar workers? Are they the "real" ones whose wisdom you absorb? Do they stop being real when they enter a chain restuarant?

Some locals (as if they're museum artifacts!) don't live cheaply; or have learned your language; or are overeducated; or buy in bulk; or like to travel too (can a local travel?); Are they not authentic? Not able to teach you something? You've heard from them already, I guess.
