About Txt messaging in theatres

I found it pretty sad the other night trying to Watch the Final Destination Trilogy, and people kept turning on their cell phones to answer txt messages. I even ask the people in front of me to stop, that the screens were very distracting. One of the guys told me to get out of his face. I said "I helped promote this screening, and I will ask to have you removed" He and his friends left the phones off for the rest of the 1st movie.

Why bother even going to a movie if you are just gonna spend it chatting with your friends on your phone. How can you even focus on what is going on with the movie when your face is buried in the phone.

Now the question is, what can you do? I would like to see announcements made that says "please turn of cell phone and text messaging devices. Those using them during the presentation will be asked to leave"

I wonder if we can get enough people to write and complain about the problem if the theatre would take some sort of action. The theatre has security. They could walk in and do spot checks. Post signs.

Do you think it would help or work?
