A couple of years ago, my wife asked that we drive a few miles to hear a gospel singer she has sung in back-up group for. Soloist with pianist, not rock oriented at all, in a mid-size church. Some fool cranked the volume completely over the top, and I, like a fool, didn't exercise my perogative to leave. The next day on the way to work, I kept trying to figure out what the whistling sound in my car was. I found out, all right; I have never been without it since. I would have sued, on principle and in hopes of saving someone else the misery, but how the heck would you really prove something like that in court.
IF IT'S THAT LOUD, IT'S TOO F**KING LOUD!
