Did you tell them you thought the train was entirely guard-less? That'd be new. Combined with stating your origin as Cardiff, they may have thought you were pretending not to know how to buy a ticket... and hence avoiding the fare?I said ' Did you make any effort to find the guard on the train?'
He said ' No i didnt make any effort ' (this is bcaus im used to guards walking up and down the train for tickets and when they didnt I assumed there wasn't one on board.)
I dunno, I have never actively tried to seek out a guard before in order to buy a ticket and I don't think this should be the responsibility of the passenger, especially if they are sat in their cubby hole, but in this case, I think asking would be a priority.
