I'm Sorry, I Can't Eat This Salad.

I usually if somebody makes a mistake of like, oh, it's the wrong dressing or they put cheese on a backstand or I'll just like eat it. Like, Hey, could you just switch this out? I'm sorry that I have to send it back, but I can't eat it. Do you send more things back as someone that has some like dairy intolerances and whatnot?
