(I’m showing a customer the difference between a few different products and the benefits of each. After a few minutes, he selects the item he wants.)

Customer: “Why are you so smart?”

Me: *jokingly* “Everyone tells me to stop, but I guess I just can’t help it!”

Customer: *completely serious* “Well, stop it! It annoys me when people are smarter than me!”

Me: *speechless*

Customer: “Kids these days!” *walks off*
