Math, no, you’re not. In fact, I’ll usually be able to fish out the $.33.
Maybe it’s 'cause I’m a poor college student, but I do use my change. I’ll pay exact change when buying little items. When I had to go to the laundromat, I’d save up my change for the week to pay for it.
I like coins and I like bills. I think money in general is good. I’m too broke/too stingy to just be throwing it away.
