“Would they do that for Kosher customers? Oh, I forgot. They don’t serve Kosher food.”
There are Kosher McDonald’s in Israel, and I believe one in Buenos Aires as well. None in the US, that I know of. There are a number of Kosher Subway restaurants in NYC (and perhaps elsewhere). If it turned out that they were selling non-Kosher food, my guess is they’d be sued as well.
Don’t confuse them with facts. Never mind that conservatives should be against fraud and misrepresentation.
