So you are in a theatre and a couple kids sit down and begin engaging in a text-a-thon, following it up with some arm wrestling and a conversation where they attempt to equalize the conceptual difference between the two of them -- a complete transference of information would require more viewings of
more movies, and you know you'll be around during this process, as you live in a finite township.
You are too lazy or too passive to get up and tell them to shut up.
What if you had a keypad on your arm rest? Keying in the seat number of the nuisance would send a sharp shock to their backside. Not dangerous - more like a static zap. But that's just you.
Since anyone can have the power to zap anyone else, you risk hoodlums showing up at movies just to passive-aggressively show their passive dominance, by zapping everyone repeatedly all the way through the film.
To eliminate this, each seat can only trigger a single zap during a viewing. This way a hoodlum will only be able to zap someone once, without having to get up and move to another seat, which would likely be more active then his passively-aggressive personality would allow. Also the seat would most likely be filled.
But everyone else can zap the hoodlum once. This means he could be zapped a hundred times. If he is a chronic communicator, this would show him how his actions are unpleasant to the temporary movie viewing society within the theater. If he is a chronic hoodlum, he would get a taste of his own medicine.
I get the impression this very half-baked idea has been already half-baked before. It was also partially stolen from a short story I read a million years ago about buttons everyone had that allowed them to kill one person on the planet. Would you push your button or not? But that seems extreme for a theater, especially with the loosening of the bowels.
