Spreading the music

On Friday, I had to drive to downtown Chicago. Typically I drive once or twice a week as part of my job.
As i was leaving the 5 story parking lot, I noticed that one of the attendants (who was between 55 and 60 years old) was helping check people out. This is a bit unusual, since everything is automated and you pay for your ticket prior to exiting.
It seems that the swipe card at one of the exit stations was having problems, so this guy was helping people.
I was behind about 6 or 7 cars and finally pulled up to the exit to swipe my card. Ball Peen Hammer was blaring when I pulled up. This is what I heard from the attendant: "yeah, your music is alright!"
I pulled away with a smile on my face, and couldn't help but think of the trash he must have been hearing before I gave him an earful of Joe!
