A supermarket in my neighborhood, Giant Eagle, has two types of shopping carts; the normal long basket, and a tall, upright cart with two shelves on it. You use a normal cart for shopping, but after you purchase your groceries, the bagger transfers everything to one of the tall, upright carts, which you're supposed to use to take everything back to your car.
I hate these upright carts -- the rear axle is placed where it hits your foot or the bottom of your shin unless you're very, very careful when you push it. I have never seen another grocery store use this two-cart system; only the Giant Eagle in Legacy Village outside of Cleveland. What I'm wondering, though, is "what's the point?" Why have these special, awkward carts to take your bagged groceries out to your car? Why not just use your normal shopping cart to take your purchased products to your car? Are there any other stores that use this dual-cart system?
