Bought a Railcard for a journey to Manchester, must've accidently bought a network Railcard instead of a 16-25 one. Got checked thrice and the conductors didn't mind or even mention my blunder so I was still oblivious. Then, on my return trip got checked by a conductor and charged £78 for a whole new ticket as I had the "wrong documentation" - just say wrong Railcard you pillock - so couldn't even just make up the full cost for the ticket I already had. This was east Midlands rail.
Is this a case of a cock of a jobsworth or am I in the wrong for trembling for want of skinning the twat alive.
