Or how about the theatre just has a policy if you are caught using your cell phone and it's disruptive you get booted with no refund. It's free and maintenance proof technology.
I don't agree about the "if you go to a theatre then you shouldn't need a phone".
Ok. So what if I have a date night out with my wife and we leave our kid with a babysitter and the child has a major allergic reaction, accident, ect and they need to reach me ASAP? Should that be blocked too?
Common sense and common courtesy are all that are needed. Turn your ringer off and keep it closed unless something emergent happens and you need to leave the auditorum. If you can't follow those rules then you should be escorted to the door.
