My sister and I need to get to Narita and were not interested in luxury or following proper procedure.
So at the Tokyo statio we jumped on the Narita Express without tickets and sweated until the doors closed.
Once the train started moving, they wouldn't kick a couple of deadbeats off until we got to Narita.
Eventually the conductor came by for our tickets. He simply told us how much it would be for a standing ticket and charged us.

So much for getting into trouble. What a let down.
Anyway, this guy shared our seatless journey.
