Although this particular case appears to have ended correctly — with an apology from the heavy-handed enforcer — it does still illustrate just how far the copyright police are willing to go:
A shop assistant who was told she could not sing while she stacked shelves without a performance licence has been given an apology.
Sandra Burt, 56, who works at A&T Food store in Clackmannanshire, was warned she could be fined for her singing by the Performing Right Society (PRS).
However the organisation that collects royalties on behalf of the music industry has now reversed its stance.
They have sent Mrs Burt a bouquet of flowers and letter of apology.
Mrs Burt, who describes herself as a Rolling Stones fan, said that despite the initial warning from the PRS, she had been unable to stop herself singing at work.
