This is pure BS.
When I go out to eat I request that dishes that include pork (like the Cobb salad) be made without pork. I can’t eat pork because it’s hard for me to digest.
I’ve done this many times at TGIF and not one server has ever raised an eyebrow at me.
I’m sure Jewish people and others with digestive problems have made the same request.
You said "hard", not "impossible".
If it were "hard" for me to digest, I would just might eat more in the hope it would become easier.
