Should all Japanese directly address foreigners in Japanese ?

[quiet sunshine]

What's foreigner's proportion in Japan? And what's foreigner's proportion in western countries? Among those foreigners, how much is the proportion of people who can fluently speak the language of the coutry he stays?
May be westerners have the impression that all foreigners can speak their language but Japanese have the impression that most foreigners can't speak Japanese so they usually assume they can't?
You suppose Japanese' psychology in your thinking way through your experience, how do Jananese think about this issue on earth? Hm, there should be some real Japanese to participate into discussion.
Anyway, even if it would be "discriminatory" as you thought, I think it would be "friendly discriminatory".

Have you ever considered that the people who have it happen to them often enough and over a long enough period of time for it to begin to irritate them aren't short-term tourists here?

To those who first know you, they may contact with you according to their general impression about foreigners. You contact many Japanese everyday, but to many Japanese you contacted, although they might contact foreigners before, it's their first time to contact with "you".
