when you're eating out and you want to know whether a particular dish contains something you're/your DC are allergic to, would you ask the person serving you before you ordered it if it contained x? Or would you just order it and then kick up a fuss afterwards when you realised it contained the ingredient you're allergic to and make a fuss about not being told it contained it?
I imagine most people would go with the first option, no?
I know this is an odd question but I do have a (very boring) reason for asking.
