Failure to Recognize a Creepy Receipt

I went to Target to buy face wipes tonight... with tax, the total came to $6.66. My immediate compulsion was to buy gum or mints to get around that omen, but I resisted. Instead, I said "that's kind of creepy." The cashier looked up and said "yeah, those wipes are kind of expensive, aren't they?" It was very difficult to stifle a smile at her failure to recognize my attempt to be clever. I guess humor is in the ear of the beholder...
