It was bound to happen at sometime. First, some background. I'm a freak. I happen to like mathematics. I relax by doing formula in my head. Yeah, it's weird inside there, deal.
I like to make change not so much challenging, but I strive to make my life simpler and my pockets less jangely, so I don't feel like my grandpa, whom always had change in his pockets. So when I was at a gas station today, and the bill came to $8.60 (Giant Eagle Gitgo, had $1.20 off, yes I waited until I had at least 8 gallons to pump). I went in a gave the clerk $20.10, thinking I'd trade up from a dime to two quarters; instead of having my dime, plus a quarter, extra dime and nickel. The clerk punches in the number on his digital register and gets a look of astonishment on his face. Don't say it, I think hard at him.
"How did you know it would come to $11.50?" he asked.
"Mathematics," I replied after a second, trying to keep from screaming. I see that this answer on confuses the clerk. "I used to make change before these new fangled digital thingies were around," I continue, and that seems to satisfy him.
I had to leave before I laughed out loud.
