Have you ever travelled in a train without a ticket?

@TheSirfurryanimalWales But the law says you must have a ticket before you travel.

@MartinII Yes-but in the days before ticket machines( and online sales) if the ticket offices were closed you had to buy on the train.
Still the case if there are no means to buy a ticket at the station.
You don't have to buy online.
So I've had several late night trips to my local station free of charge.
On occasion the conductor simply didn't bother selling tickets.
Others he had to sell so many he never got to me.
