Pumping gas? Have some meaningless commercials blaring at you. Wait at the doctors? Have some hospital commercials blaring at you. A/C systems are often brutally loud.
Pro tip: one of the grey unlabeled buttons next to the screens on gas pumps mutes the audio. Muting those ads every time I pump gas feels like a subversive act in a dystopian Bladerunner-esqe society where ads are inescapable unless you know the hacks.
Yes, it is usually the 2nd button from the top. I've usually found it on the right side.
