When I reacted to a cosmetics product and attempted to return it the closing store manager - a smaller, angry looking fellow with a lot of facial hair - told me an allergic reaction wasn't a valid reason.
I walked out of there holding the product I couldn't use along with a receipt, and the intention to warn others NE's a downright stingy operations unconcerned about customers once capital is made. This was a foul move by the manager in charge.
