This might just be me, but I've always found that TVs in public have this weird pull to them. Even if I have no feelings at all about what's on the screen (a soap opera I've never seen?) my gaze is still repeatedly drawn to it. If there's one around I generally try to position myself so it's not in my peripheral vision or I have to spend some effort ignoring it. It feels like whatever it is that keeps kids, as we say, "glued to the screen" doesn't always go away in adulthood.

I would definitely find it relieving if someone showed up with a TV-B-Gone and clicked it off.
