Have you ever caught your employees dancing in the aisles? How about singing? Maybe such fun should be encouraged.

This video shows how delightful having a bit of fun can be, courtesy of English grocery store Waitrose and the Scala' food brand. The businesses staged a "shopera" with five secret opera singers breaking out into song in the aisles.

London Loves Business reported on the inspiration for the opera promotion: Sacla’ UK MD Clare Bampied said: “Sacla’ aims to bring home the spirit of Italy, and inject some Italian passion and flair into the everyday lives of people in the UK - what better way to demonstrate this than with a Shopera?”
