Paper or plastic? or Jingle Bells?

Today's crumb is a short, joyful video contributed by a loyal reader near Indianapolis, Indiana, USA. Born in Germany, she explains that EDEKA is Germany's largest supermarket chain. One of their stores prepared a surprise for Christmas shoppers. They hid 13 cameras, and switched off the lights one day as customers waited in lines to check-out. Cashiers continued to scan items through check-out when suddenly the scanners began beeping a familiar tune! The cashiers had choreographed a holiday classic to the delight of shoppers. This video is guaranteed to make you smile.  www.youtube.com/watch?v=H965m0Hkk5M
