      Just as a quick context. I work in the fast food industry and normally close to closing time the kitchen staff like to play music while they clean. This is usually on phones in a plastic cup close by them so the rest of us don't have to hear it and they can make the cleaning less tedious for themselves. Well, (for sake of reference he will be called "Country") unlike the rest of us, Country uses a Bluetooth speaker and has religious country music playing at almost full blast. 

      After being the one who ends up gathering at least 6 complaints from customers in the lobby I decide to wait until he wanders off and re-sync his speaker to my phone and have "mudvayne ~ Dig" (really loud aggressive death metal i know of from a buddy) paused and waiting. 

      The moment of the play button being pressed by him was likely the most beautiful sound ive heard in awhile. The customer i was speaking to about the issue had already known about what I had done and thanked me afterwards before leaving. Country then turned the speaker off completely after the surprise and was in the break room for the rest of the night on his phone but the rest of us had gotten blissful silence.
