Shopping carts. A curse, or a blessing?

So apparently people at places with shopping carts don't like it when said carts are left in the middle of the lot. And can you blame them? They roll around and damage cars and suck. And the employees have to put them back. But are they all bad?

The answer is no. Carts that are left in those long strings of dirt in the middle of lots are good, because people can park by them (or park near them) for added convenience in getting a cart. I say employees should leave these in the lot to give people this added convenience. Plus, the people just might put the carts back later. And in case they don't, then it's no harm done. So everyone wins. Just don't leave your damn carts in the middle of the lot.
