Hey Pandas, What's The Most Awkward Thing That Has Happened To You In A Grocery Store?

Years ago I worked as a Courtesy Clerk (bagger) during the holidays. I was bagging the groceries for a very petite and gracious elderly lady. As I was finishing her order I asked her if she was ready for Christmas, as was customary to ask each shopper back in the day. She looked me straight in the eye and said "F**k Santa" and pushed her cart off without another word.
