I think by now you recognize this guy.

On a crowded green and yellow line train pulling up to a very full Chinatown/Gallery Place platform.

Driver, in a very reasonable tone: "alright now, you people want to get off this train onto the platform. There are a whole lot of people on the platform who want to get on this train. [perfectly timed pause] There is a conflict there. You people on the train, however, have the upper hand. Use it responsibly and have a great day"
