In many grocery stores the checkout lane have two people: the cashier and a 'bagger' who will bag the groceries for you and, if requested, will bring them out and load them into your car. The bagger sometimes gets a tip, especially if they are handling heavy items like cat litter. (Baggers are common in grocery stores with large parking lots: so they were common growing up in a mid-sized city in the Midwest but I've never seen one in NYC)
