Grocery stores that don't let you take carts to your car. I'd never seen them until I moved to the East, but I still can't figure them out. Am I just supposed to leave my already-purchased groceries just sitting there, unattended, while I go get my car? I don't think so! It really makes me angry. By the time I got to my car, I was kicking the toilet paper while the bag holding cans broke. It was really as pathetic as you picture it.
Things that Must NOT Go:
Clementines. Along with bananas, they are the perfect fruit.
