She almost shrugged as she put my amount into the cash register, and I could see how surprised she was when the change amount came back as $5.50. As she handed me the change, I could see on her face the question “how did he do that?”

This happens far too often. My wife says it is because children no longer really learn math in school. They get to calculators quickly. Memorize the times tables? Do long division by hand? Figure out percentages? It seems like these are relics of the past, like learning cursive writing. This is elementary school stuff, and it looks like one can graduate high school without learning them.

Mental math seems to have gone the way of the Dodo bird.
Not giving you grief, I think you meant to say two singles, or $15.52. As got $5.50 back, clearly you got it right at the time.

I have encountered this phenomenon also. I ask myself, is the first time they have seen this? It's the same thing - an incredulous look and they try to give me the extra money back. 'Please dude, it's less than $20, all you need to do give me is a twenty.'
