Conductor: Stand clear of the closing doors. Person in the back of the train, step out into the train. Step into the train! Excuse me, in the back with the grey shirt, step into the train. Yes you! I’m looking right at you! Oh my god! Ladies and gentlemen, we’re being held in the station because someone in the back of the train wearing a grey shirt is blocking the doors.
Conductor [as passengers keep blocking the subway doors from closing]: You’re invited!
Conductor: Stand clear of the closing doors. [Alert signal, doors re-open.] Goddamit! There’s always someone… Isn’t there?
Conductor, in completely empty train: Ladies and gentlemen, if you get to the train and it is full, don’t try to force your way in. Don’t block the way of the door closing either. I don’t want any body parts obstructing them. Also, if you get to the train as the doors are closing, don’t try to pry them back open. Don’t try sticking your arms in between them either. Very bad idea. Just stand on the platform, wave, and say: "Bye bye, train".
Snarky train conductor: Ladies and gentlemen, your attention please. It’s very simple: We open the doors, you get on, we close the doors. If you are going to walk past two or three doors trying to find a car or space that you like, don’t be surprised if the doors close on you before you can get on. We are not mind-readers.
Conductor, to guy holding train doors for his girlfriend: Sir, please let the doors close, we can’t wait for your girlfriend. [Some time passes.] Sir, you are young and not unattractive, I am sure you can find someone else to sleep with you on the train.
