<p>Gonna travel way back in time here to the way it was done at the supermarket my mom shopped at when I was little. I don’t recall who did the bagging, but the bagged groceries were placed in a numbered bin and the customer was given a chit with the matching number. Then the bin was sent on a conveyer belt that carried it outside to a waiting area. You’d drive up, hand the employee your number, and he’d load the bags into your car. That was nice, especially on a rainy day!</p>
