I was standing in the check out line at Wal-Mart one day and a women had her merchandise in bags and was heading out the door. There was someone standing at the door and asked her for her receipt,she dug through pockets and her purse then told the individual at the door she must have dropped it and was going back to look for it. She never did come back, she had taken bags to the store with her and bagged merchandise hoping she could get out without anyone checking and she had a cart full of stuff.
