I was on a train to London a few years back. This one guy was one his phone for ages, yelling his head off and really annoying everyone else. After sufficient grumbles he moved into the corridor area but left the door open so we were still all treated to his business deals. Anyway, he got louder and louder and his phone seemed to be ringing constantly, then this one guy totally snapped. He walked up to the bloke on the phone, grabbed the phone and threw it out of the door window. He didn't say a word, just went and sat down again. He got a round of applause from the rest of us and the deprived phone user didn't dare argue, he slunk off to another carriage.

With the new trains it would never happen as there's no opening windows now.
