As long as it is paid for I would not mind. I can't eat gluten, maybe they could switch to gluten free pizza or sushi?
It's basically like knocking on a door at random and asking the person who opens it to eat something you're giving them... Accepting sounds like playing Russian roulette.

I guess that's not a good thing, though.
