Mirror Image
I worked at a retail clothing store many years ago. A guy came in and asked where our our mirrors for sale were. I apologized and explained that we didn’t sell mirrors, to which he replied angrily, “Well, what DO you sell, then?”
I gestured at the racks and racks of clothes surrounding him and said, “Clothes. We’re a clothing store.” He rolled his eyes and yelled, “What kind of a place is this?!” Then he left. It’s been about 15 years and I still think of that encounter frequently. Story credit: Reddit / ArethusaRay
