This happened to me recently, I asked a man of probably the age of 40 if checking Facebook was really important right now.
He'd been scrolling through his timeline for a few minutes before I said anything, he put his phone away and started watching the movie but started checking every setting for iOS shortly after which I spoke louder so everyone could hear that he was being an annoying prick.
