That is, until you have already arrived home and realize that you left the case of water on the bottom of the cart. I called the “mall” to let them know what I had done, they said no one had brought it in, but that I could bring the receipt in and they would take care of it. That was a nice move, especially since it was my fault. I drove right back across town and parked as close to the same location in hopes that perhaps I would see the same cart untouched (for the last half-hour or so). Wrong. Not a single cart at that return. And I did not see a single cart with a case of water in the stack the cart-collector had gathered. So someone got a free case of water, I hope they needed it. I went in and got a replacement case. Done. I do feel pretty dumb having driven across town to get that, after I was feeling pretty smug about using my cloth bags instead of plastic. Way to be green.
