I like to think they appreciate being able to focus

When I still went to the barbers some years ago they usually just talked to each other and left me in peace (to read my Donald Duck comics).

Lithgow did such a good job ensuring his legacy. I definitely don't immediately think of a horrible bigot the moment I see him instead of 3rd Rock and Buckaroo Bonsai.

My barbershop has a "silent service" box you can tick when making an appointment. I love them for it.
