Barber shops and doctors' waiting rooms are hellish for me, since I can't not-hear the radio/TV they usually have playing.

In France I have yet to go to a waiting room with a TV with the sound on; I think people would get upset.

I went once to a dentist with a TV above my head (sound off); I refused to sit in the chair until it was turned off. The assistant sighed and said "everybody asks the same thing, I wonder why we installed this".
