LOL. Gotta’ love it!
I hope the kids in NYC got their meal for free, at least, after that little snafu.
I grew up hearing two languages in my family. One on each side. And yes, they DID speak it in front of us kids precisely because they knew we didn’t understand it.
That way they could talk about all the family dirt without us knowing.
IMO, in this day and age, any ME looking men who speak a ME language in an airport or on a plane, deserve what they get. English may be difficult for some of them, although it shouldn’t be for someone who’s an American. But if they’re fluent in English, or can even carry on a conversation with the flight attendant, it behooves them to use English to demonstrate that they have nothing to hide.
They can practice their language at home, or in their own communities, where people can understand them. Doing it on a plane is not the brightest idea going.
And for anyone ready to flame me, if I knew I was going to be spending any significant time in a foreign country, I WOULD learn as much of the language as I could and use it.
