Yeah, because there's absolutely nothing bad that can happen when a local commercial plays at literally TWICE the volume of the programming bookending it. This happened to me earlier in the year while watching a football game - fairly standard audio level of crowd noise with guy talking over the top. Then, obnoxiously loud fast food commercial that had me jump off the couch, and fumble for the remote until I could find the mute button. I had a headache for an hour after that.
I actually called the cable company office and complained, not that it did anything to prevent it from recurring. Needless to say, I'm not eating at that restaurant EVER again.
