Romantico and others-
I think the idea of carrying a cell phone jammer is just as bad as someone who texts during a movie. Who are you to tell people when they can or can not use their phone (outside of a movie, concert, musical, etc?) If you are in the public then you should expect to deal with the public and whatever they feel like doing, as long as it's legal.
I sit in the back row of a movie theatre and always turn my cell phone on silent. Usually when I go to a movie, it's one I've chosen to go to, but sometimes in a big group I get dragged to something (like Battle: LA). If I think the movie sucks, and I'm in the back row, then I will definitely text or check my email. Does that make me a bad person? No.
I once had a guy chew me out for texting 20 minutes before a concert started, and told me he hoped I'd put my phone away and that I should actually do that now. I told him that I was well in my right to text message, that if the noise was bothering him I'd put it on vibrate or silent, but that he had no business telling me what to do before the concert was even close to starting.
And the argument that doctors or anyone shouldn't go to a movie when they're on call is asinine. When I have a new employee closing the shop for the first time by themselves, I leave myself relatively available. If I make plans I tell whomever I'm with to not be surprised if I have to answer a text or a phone call. Are you saying that I should instead sit at home and amuse myself in some other fashion instead of going out with friends? Are you saying I should kill my social life so that my job can reach me without distracting others? Because if so, you need to get a reality check.
And if you think I'm saying this and that it makes me part of the entitled generation, you're greatly mistaken. I don't expect the world to be handed to me on a plate. I don't assume that I'm always correct. I just know what to expect when I'm in public and which battles are worth fighting.
