Shopping cart, buggy, trolley, that metal thing that carries your items around a store. It can even go so far as assisting you in that tiring journey from the store to your vehicle, making sure your precious purchased items are left untainted. If the cart assist you in such a manner why would you leave the cars anywhere and every in the parking lot? Oh I'm sorry I completely forgot, the journey from the store to your car must have made your legs incapable of going that extra few feet to put the cart in the proper place. There is a reason stores put cart returns throughout a parking lot, don't be a moron. Use them.
