In the grocery store. I go into a self-bagging lane. Usually I hate self-bagging lanes, but this one had a much shorter line. I make the guy give me extra bags, and proceed to double bag all my purchases. This old lady at the other belt stares at me: "So THAT'S how you double bag!"

WTF? She's 80 and she couldn't figure out how to double-bag? That was my first time bagging other than at self-checkers which have their own bagging racks, and I was all alone. She was with a gentleman who I will judgementally call her husband. So they are two people with at least 150 years of life experience between them, and they couldn't figure out how to double bag? With two people?
