Our local grocery had that in the 1960s. As a toddler, I was fascinated by the mini-railway consisting of noisy steel rollers. It ran inside along the front wall behind the check-outs, did a u-turn thru a small hole, then outside along the front wall. A worker on the inside packed your groceries in brown paper bags and placed them on the rails. Another worker outside would load the bags from the rails to your car trunk when you arrived. Wow, that neuron hasn't fired in a long while.
