Is is rude for them to give me food past the expiration date?
It depends on what kinda of food it is. If it’s refrigerated then be sure to use it soon. But with everything else some people keep stuff past the expiration date and others even buy things a day or two before it expires. But like I said it depends on what kind of food. If you don’t want the food or if it’s smells funny, throw it out. I’ve kept cakes mixes a year or more and they taste fine. But when it comes to giving it…I usually give new food so they have longer to us it if they don’t want use it at that present time. So to answer your question, yes and no. If you don’t like them giving food then say so! Say you don’t like that kind of food.
