Shopping Carts
We humans have some baffling little habits, and not returning shopping carts to the stand is one for the anthropology class. It’s not because we are pressed for time. We are happy to spend forty minutes every day back and forth in our oversized minivan to go to the gym and run on a stationary treadmill for another forty minutes. But we will not spend the extra forty seconds to walk an empty shopping cart back to its rightful place.
