REALLY..?? HELP ME WITH THIS..!!

So I go to the store and buy a pound of sliced ham in a plastic container, a loaf of bread in a plastic bag, a gallon of milk in a plastic jug, a pack of napkins in a plastic wrap, a store-made salad in a plastic tub, and a plastic bottle of mustard AND ketchup 
--- but they won't give me a plastic bag to carry it home because the plastic BAG is bad for the environment..?????
