That reminded me of the owner of a well known cheese steak sandwich place in Philly (?). Geno’s posted signs that stated all orders had to be in English! ....He caught some grief for that from some groups, but stuck to his rule and was given cable news coverage (which didn’t hurt his business).
Knowing a second language is great, but if you don’t know English, you should be out of luck
