A day after the record-breaking film was released, commuters spotted the hilarious message written on a service update board at the Canonbury London Overground Station on Friday.
"Attention. Anyone caught travelling without a valid ticker or Oyster will be told the ending to the new Star Wars. (and also get a Penalty Fare)," the message read.
Even at Earl's Court, another message, though less threatening, has been posted.
So all Star Wars fans based in London, you better make sure you have a ticket while travelling, because the 'punishment' is so much worse than just a penalty fare.
