If a person smiles because they get used to doing it on some occasions, rather than because they're amused with something - it's still NOT a fake smile, for it comes from inside, and the person isn't told what to do; while it's a known fact that smiling faces make up your mood in a much better way than those saying "what the f..k do you want", so I prefer cultures that encourage people to smile; anyway, it's rather stupid to come to LIVE in a country and complain about something the local culture features; there are over 200 countries on this planet, and even if one's a radical commie/dictatorship lover, etc., they could still pick a country that would totally fit them.
