True story:
Last week I went to the store to get some groceries. I had my cart filled 1/2 way up and left it to go get something I forgot in another isle.
I returned, threw the items in the cart, and continued to add things for another three isles.
Half way down the 4th isle, I noticed two boxes of Ho-Ho's in the cart."I didn't get these!" I thought. Then I looked at the rest of the items - I had taken someone else's 1/2 full cart! Instead of returning it, I left it and went to get my cart.
On the way out, I saw a VERY elderly lady complaining to a man in a tie (I assume a clerk or something) about someone stealing her cart and she's too weak to walk through the store again. The man took her shopping list and went to replace all the items.
I laughed and felt like a jerk all at the same time. If they review the security tapes, I'm screwed
