I walked into a small very old wooden jewellery shop in Tawaramoto Nara.
I called out "Sumimasen" I wanted to enquire about a new watch battery.
the old geezer walked out and said, "Hai" "Gaijin-Gaijin, Out-Out".
That was the only time for me. I found it funny
My US colleague also had the same experience by an old lady in an old Nara Town. He went into a smal video shop.
It's common in Japan to discriminate against foreigners. That is certainly not a secret.
Six years, I saw a lot..
Onsen towns are the worst.
Then of course Japanese are also discriminated against. Take Barukim people. These were the animals they did the dirty jobs.
However, I guess if Japanese, it just becomes normal to discriminate. If you grow up with something you are taught, what esle do ya need to know.
