Somehow I don't see a boycott of a "teriyaki joint" in a relatively remote area making any lasting statement. Even if successful they'll just change the name, put a different family member in charge, and business as usual.
This incident has been examined in the news and on most WA state "Gun Boards". The owner claims it was a misunderstanding brought about by language issues.
Regardless I'm not driving a few hours to go see if the issue remains. Since I never went there to begin with, does my not going there now count as a boycott
