Hit the grocery store on the way home today. As I was leaving, I saw a worker tranining a new employee. She was showing him a feature on the shopping carts that I had never seen before. She said most customers have never noticed...but if a shopping cart is full, there are places designed on the carts to hang extra bags (as pictured below)...
Maybe it's just me, but I still find myself riding shopping carts as I leave the super market with a full cart. You know how it is feeding a family - overfilled shopping carts.
