I'm to the point I would pay a lot of money for a compact portable "jammer".
This sounds awesome. Of course, I would only use it in the case of rudeness. Some people don't even have a concept of manners in public any more it seems.
Anyone that has been on the forum a while knows my feelings about rude people. I have threatened to throw cell phones overboard in the past. My chair saver's collection of towels grows with each cruise.
