I sort of already am. High school job was bagger at Kroger (in suburban Detroit). Literally just started working at the Kroger fulfillment center in Groveland, FL, yesterday. One of the tasks I may or may not be trained for is pretty much putting groceries in bags (in bins). I have been trained in loading the bagged/binned groceries into "carts" and loading into vehicles headed toward the customers' homes.
