Math Has Been Working For At Least That Long, Yes
I’m at my local roller derby game, and I decide that a beverage is just right for the occasion.
A local brewery is supplying the beers, and the bar is run by skaters from the league.
I buy two beers, and the total comes to something like $18. I hand the lady a $20 and three dollars in change. She looks at me weirdly and says, “It’s only $18.”
I reply, “It’s so you can give me a $5 note instead of coins.”
“Oh! That’s clever. Did you work it out when you were queueing up?”
I just let it slide, thank the lovely lady, and leave with my cans.
