Ken Livingstone did not get off, he paid the fare, like 10 other persons on the same train; and has got humiliated by the press in front of the whole world. So you call that getting off, no. And the train company was right, rules of natural justice dictate that as a first offender, he should be given the opportunity to make good on the fare and if he then failed, he'd have to fined. Don't make a meal out of this, it is a perfectly human thing for one to forget; although I would not dare myself as they once ejected my husband rather roughly because his travelcard was not for the zone that we were travelling in (we didn't even know that!). Still, they did not fine him but asked him to pay the difference for his travelcard, and we were able to continue with our journey.
