At my Subaru dealership, they don’t play any music, but they do have a TV (tuned to Faux News) spewing venom to anyone who might be in the waiting area. Aside from the toxic political content, the volume of the audio makes it difficult for me to concentrate on the book that I always bring with me when I am in a waiting room situation.
Luckily, the remote control for that TV is readily accessible, so if there are other people in the waiting area, I ask, “Does anyone mind if I reduce the audio volume?”. It seems that everyone else in the waiting area was just waiting for someone to have the gumption to take the initiative, and the other folks always say, “NO, please turn it down!”.
The best times are when I am the only person in the waiting area, as that gives me the opportunity to just shut the TV off.
