Twenty years ago, Minnesota embraced the warehouse-style grocery store concept. With wide aisles and stock packed to the ceiling, these super-stores sold merchandise in bulk packages, with sales volume to match. Shopping cart size grew to accommodate these new bigger consumer purchases.
Minnesota winters are tough and collecting shopping carts from the parking lot after a blizzard was challenging and potentially hazardous. Just picture one or two part-time high school student employees maneuvering 10-15 carts into one huge line, then pushing them up an incline back into the store in slushy ice and snow. Cart collection became the worst job in the supermarket… but, it had to be done 24/7.
