Way back when, I did the grocery shopping for my large family as a teenager. Mom didn’t drive, dad didn’t shop. I drove, so she send me for groceries. Deal was I could keep the coin part of the change from the purchase for doing the shopping for the family. Didn’t take me long to figure out to ask for a $10 roll of quarters each time when I was given change.
Went on for a few years; Mom didn’t know about it until I fessed up in my 20’s. “You little s**t,” she said while laughing.
I miss her.
