I forgot to scan something at Sams Wholesale a few weeks ago completely by accident. My in-laws asked me to pick something up for them when they found out I was going to Sams. I had a buggy full and went through the self checkout. I thought I scanned everything in the buggy however when I got to their house to give them the item I looked on the receipt to check the price so they could pay me for it and it was not there. I have no idea how I missed it. I guess I need "training".
