"the young people who do so must find the pop music keeps their spirits up"

It's kind of you to think so Eliza, but always when I comment to a worker that the music is bothersome, the reply is "Oh, I don't even hear it!" And I believe them. Waiters, managers, etc are so busy and distracted that the music doesn't even register on their consciousness. I'm sure it applies to caregivers too.

Meanwhile, I'm sitting at a table and can hardly hear my husband talking to me.
