I have often been in a business dinner situation where someone offers to order from a list that includes shellfish (I'm allergic). I don't make a fuss. I just don't eat them.

I was reminded today about a situation in which a woman ordered a steak very well done in a small French restaurant. The chef refused to do so. She raised a fuss. It goes without saying that we didn't ask her to dine with us again, ever, anywhere or any time!
