A member of staff at Waitrose in Bracknell entertained queuing shoppers as they waited to go into the store.
Louise Crawford usually works behind the welcome desk at the supermarket but was asked by her manager to sing to customers.
Louise treated shoppers to a rendition of Irene Cara's classic 'What a Feelin' and her performance was shared online.
The 29-year-old has sung to holidaymakers in hotels and on cruise ships around the world.
