Yes but some foreigners speak so well on the phone it cant be detected they are a foreigner.
I can't view the website because I'm overseas (they blocked overseas IP's?), I have used JK-style in the past so I imagine it would be similar.
I can speak Japanese (N2) but people can detect that I am a foreigner. Is this shop a total no-foreigner policy, or foreigner-who-can-speak-Japanese ok policy?
