6. Mobile Phones
Babies generally can't help it when they cry, but adults with active mobile phones and working consciences have no excuse when their telephonic communication device starts to ring halfway through the movie. Because the cinema is virtually covered in 'Turn Off Your Mobile Phone' signs. There are even adverts within the adverts dedicated to preventing phones ringing out halfway through the film. Aside from that, it's just an unwritten rule that you don't make your own noise through a movie - something about other people paying to watch a film, in order to actually watch the film. And yet, in spite of all that, some reprobates still decide to let their phones remain active and ring-happy when the curtains go up at the cinema. Some kindly put them on silent, but that's not much better; people still text, buttons still rattle, the LED light still glows. If you're texting, you're not enjoying the film. If you're not enjoying the film, then GET OUT.
