Shopping Carts

It's a mystery to me.

You go to the grocery store, park in the back section of the parking lot, and walk all the way up to the store. You pick up a shopping cart and continue to walk all the way through the store to get everything you need. You make your purchases and push your grocery-laden shopping cart all the back to where you parked and unload all those groceries into your vehicle. A shopping cart return station is six feet from your car, and yet you leave the cart sitting exactly where you put it so you could easily reach the car with your groceries.

Is walking that much of an issue for you? If so, why didn't you park in one of the many open spots closer to the store?
