Car repair chain sued for playing radio

James Glover says:
Kwik-Fit, a British chain of car-repair garages, has been taken to court by the Performing Rights Society for "public performances" of music played on staff radios.
The PRS claimed that Kwik-Fit mechanics routinely use personal radios while working at service centres across the UK and that music, protected by copyright, could be heard by colleagues and customers.

It is not entirely clear is the term radio is used to refer to broadcast radio stations or to CDs/Tapes payed on audio equipment. Either way this seems a ridiculous abuse of public performance licenses.
