what do these people think they're doing, who
a) crank up the stereo volume in their internal combustion transportation vehicle to the point that with their windows closed and my windows closed, at 10' I can still hear it?
b) talk on their cell phone on the bus for more than a few minutes loud enough that they can be heard 6 rows away?
c) play YouTube videos on their laptop at a coffee shop so loud as to be heard 5' away?
Obviously their parents never included "that's not polite" in their social behaviour modification process.
