Suing someone for humming copyright-protected tunes at work? You thought it couldn't get any more ridiculous:

The debacle began earlier in the year when the PRS threatened the grocery store she worked at, telling them to ditch the radio that played in earshot of customers or pay royalty fees. Missing the music, Ms. Burt decided to start singing some of her favorite tunes. She describes, "I would start to sing to myself when I was stacking the shelves just to keep me happy because it was very quiet without the radio."

 

Then came new threats from the PRS. Ms. Burt describes, "When I heard that the PRS said I would be prosecuted for not having a performance license, I thought it was a joke and started laughing. I was then told I could be fined thousands of pounds. But I couldn't stop myself singing. They would need to put a plaster over my mouth to get me to stop, I can't help it."
