Really happened!
I go into a shop to buy a watch battery. Pretty young woman clerk tells me it is $ 7.99. I so OK and clerk turns her back and starts installing the battery.
While this is going on I fish around in my pockets and come up with
$ 8.47. ( 6% sales tax at the time).
Clerk hands me the watch and I hand her the cash. Following conversation ensues:
Clerk "What is this for?"
Me "To pay you for the battery."
Clerk gets puzzled look on her face, goes to the register, rings up the sale ---- $ 8.47. Counts cash, puts it in the till, takes receipt and hands it to me, and says:
"Wow. You must be some kind of genius."

Friends and neighbors, in my long and dismal life I have been called many things by young women. But I gotta tellya. That is the first and so far only time I have heard the word "genius!"
