Wine Glasses

For Christmas I asked for red wine glasses. Unfortunately I got wine glasses but they were for white wine. I hated to return them. I find it nasty to return gifts. However, I knew they were from Kroger, so I had to find a super Kroger store and they had them.  I took the two boxes of red wine glasses to customer service and explained that I had white wine glasses in the car with no receipt, could I exchange them.  The lady opened the box and said

"These are white." I know the glass is white but they are for red wine and the ones I had were for white wine. She asked what the difference was.  So I explained.  In the end she allowed me to exchange them but I think she was blown away that I could be so trivial.
