After I shopped at a local WalMart on Thursday the 20th I got home to discover that I had left two items behind. The next day, Friday the 21st, I went back to the same store. I got the items from off the shelf and went to Customer Service to explain myself. I was told that it was all OK. I was given a bag and told I could take the items with me. No paperwork, no argument, it all went my way. I am not sure what it all means, but I got out of there before the thinking changed.
