There are many places in the world where society has attempted to eliminate mobile phone use. Commercial airplanes appear to be the only place that has successfully instituted a no tolerance policy. Movie theaters wish they could do the same thing, as do most moviegoers. Alas, they cannot sit next to every single person and force them to keep their phones stored. As a result, one of the many complaints of why people avoid movie theaters is mobile phone usage.
Most academic conferences attempt to institute such policies as well, but attendees, professors, and presenters all use mobile phones. I personally saw the chair of a panel texting throughout each presentation and even laughing in response to texts. To this day, I cannot think of that professor without remembering her rudeness.
