Tonight I went in, got a cart, and proceeded to start shopping. I put about 5 things in the cart and set it to the side for less than a minute while I picked some hummus out from the deli. I turned around and my cart (which had been less than 5 feet from me) had completely vanished. Thinking someone might have mistaken it for their own, I looked around for it. I didn't see anyone with it and I didn't see any other abandoned carts. I went back to the front to get a new cart, picked out my groceries again, and started shopping again. I found my groceries from the first cart stuck on a shelf in the next isle. So someone grabbed my cart, ran, and ditched the groceries when they were out of sight. Classy.
