Solution: Ban all texting in movie theaters after the previews start. Ban all people who keep talking during movies. If the ban doesn't work, legalize shooting these people after you give them a warning to leave, shut up or turn the device off or die. Simple solution to those with no manners. Let's get these new laws passed. It will make our lives more pleasant to know if someone doesn't have enough manners to leave a theatre after being asked politely to do so, someone with a gun will enforce the new law. More people will use something called manners or courtesy. If not, they will be exterminated. It works for those not wearing seat belts. Thousands dead each year nit wearing seat belts.
It works for thousands of people who spread the flu by shaking hands in church, thousands dead each year.
We can make this work in movie theatres too.
I guess if cinemas wanted to enforce a no texting, no talking, no electronic device use during movies ban, they could hire a bouncer to throw people out if anyone complained or monitor each room from a central location and start walking if they see someone's device activate. They might need listening devices to catch people constantly talking during the movie.
I heard an old couple constantly talking during one movie. If someone knocked them out, it wouldn't have bothered me very much.
