Yep, definitely Radio 4 here.
One of my pet hates is when I have left the car to be either:
A) Parked by one of those companies that offer a parking service when you are going on holiday
B) Having the car serviced
and on collecting the car find that the radio has been re-set to "Radio Noisy" (on occasion this has been a foreign language station, which in the UK I find particularly annoying. The parking people are driving my car for around 15 minutes max, so why???)
The chap who is usually charged with servicing my car (the garage is on the same industrial estate as where I recently worked, very handy) was a prince among men, in my opinion, as not only were his prices reasonable, but he never interfered with my settings!
