a perfect change - A perfect change is the pile of coins you bring just so you

A perfect change is the pile of coins you bring just so you can make the cashier’s day worse. It’s the amount of coins you carry like it’s your duty.

I had a perfect change and I used it because I didn’t want to be the one who got change back.

I brought my perfect change just to mess with the cashier’s head.

I gave the cashier my perfect change and I didn’t even say hi.
