Children also fall out of carts. There is no place that's 100% safe.
Good point. And some carts are in bad shape and have no belts, or the belts or torn and unusable. Or the wheels are so wobbly that they could fall off if not mounted correctly or tampered with by a 3 year old. And what about the germs on the cart left behind by previous shoppers? Falling mirrors vs faulty carts- no place is safe.
