Louise Stephan, a representative for supermarket chain Coop, confirmed the message was found on two receipts from a Stockholm location and the words were apparently added to the system manually by an employee.

Stephan said the store is investigating. She did not say whether the responsible employee had been identified or what actions would be taken against the worker.

A woman identified as Kerstin told the Aftonbladet newspaper she was shocked to discover the phrase on her receipt after a recent shopping trip to the Stockholm location.
