Followup - Following the Line to Innovation (Costco)

During the winter holiday shopping season in 2007 I was suspicious when a man at Costco asked if he could scan my Costco card while I was standing in line, thinking that he was going to try and sell me on their executive card. I was pleasantly surprised when he then scanned my items with a portable scanner/computer and gave me a slip of paper to alert the cashier that he had done so.
