In my opinion this is another STAGED scenario.
The ONLY time I have ever seen anyone get upset with someone speaking another language was when they were the customer and the employee refused to interact with them in English. 1 time about 20 years ago. Manager intervened.
My wife is from Japan - we had one incident back in the 90s where a fast food employee made fun of her because of her accent. She came home in tears. Girls were very young and only knew mommy was crying. In that episode I went and gave the manager a piece of my mind for allowing it. She acknowledged it happened but didn’t feel it was a big deal. We never returned and I told people I knew in the area of the incident.
So 2 incidents in 50+ years both in the 90s. I’ve never seen anyone customer or otherwise insist that someone couldn’t speak a language - unless to properly interact. Which is why I believe this was 100% staged for publication.
IIRC, some Dbag chick actress or activist made fun of Melania Trump’s accent once. Dumb butch had no idea FLOTUS speaks several languages.
