I have to say however the reason I don't shop with my cash obsessed "Boomer" wife anyore is that she insists on digging thu her purse to find the exact coin change at check out. Good Lord women the bill is $39.99. Give the lady two twenty's and lets enjoy the rest of our remaining days before these people behind us kill me.
You just described my dearly departed mother. She would stand in line for 20 minutes, get to the counter, the cashier would ring up her purchase, then a lightbulb would suddenly go on in Mom's brain -- "Oh. I have to pay now!" Then she would root around in her purse for the exact change while people behind us would be grumbling. I would say, "Mom, there are people waiting behind us." Her reply: "Oh, they can wait."
