The lecturer was talking about something, I was reading my magazine and then it happened, some dude flipped his shit and yelled loudly at his neighbour to stop texting. This wasn't over quickly and when I ran the numbers, the man must have balls of steel to do this in a ~300 person lecture theatre. Highlights of the twenty second rant included "Why are you here?" "will you stop texting you've been doing it all lecture".
And he's right. If you're bored, pull out some reading or leave. Don't distract others.
I only wished I could of thanked him.
