While watching the Bond movie yesterday, my cellphone fell out of my pocket onto the floor of the cinema. I didn't attempt to find it then and then. I didn't want to make too much noise, and although I had a little LED flashlight on my keyring that could have lit up the floor so that I could have seen it, I didn't use this because as a matter of courtesy I didn't want to disturb nearby people watching the film. At the end of the film, I searched on the floor and couldn't find it, despite searching for it for fifteen minutes. I can only conclude that the person sitting next to me (who left quickly when the credits started) picked it up off the floor at some point and stole it. So much for courtesy.
