This tactic is typical of the PRS these days - they go for the easy targets. There are plenty of places flouting the law, but it isn't obvious from their Yellow Pages entry.

I work as a sound engineer, and we have to pay PRS because we use a music source to test equipment in our warehouse...! This has nothing to do with public performances, or even whether there are people actually listening. As we are listed in the Yellow Pages, we had a call a couple of years ago from the PRS - and now the MCPS have jumped on the bandwagon.

We cannot escape, because we need to know a CD player (for example) works before it can go out on hire...

A bit like we have to pay a TV licence because we have TV receivers on our premises... even though we don't use them for watching TV - and neither do our clients. It's just that a VHS player has an analogue TV receiver in it... aah! After December 2nd they won't have a case, will they?! Methinks they haven't realised that, yet...!
