If it's after 10 then all aboard !

Just a quick short story for you. Whilst working the late train last night I decided to do a quick ticket check. I walked into First Class and found only one passenger in there. 'Tickets please' the lady, who was resting her head on the table, looked at me and said 'I dont have one'. I asked her where she was going and she asked why. I told her she needed a ticket. Her reply surprised me because she explained calmly that she didn't need a ticket because it was free travel after 10.00pm. Needless to say she left first class with a full price ticket and a face as long as her journey.
