back to the original story.
the official line on this is that without your railcard your ticket is not valid. How can you prove somebody else is not using your railcard at the same time?
Abiding by the terms of carriage is important. The valid ticket doesn't only validate your travel but validates your reason for being on railway property. Without a valid ticket your not insured to be there. So if anything was to happen to you then your held responsible. No compo claim for you!!!!!
Moral of the story is..........
This is your mistake, BUY A TICKET, and pay my wages. LOL
Is there really any need for that ?
The OP made a mistake, or two and got upset about it. Of course this is that old chestnut if you buy a railcard reduced ticket you need the railcard. Though as it does have a photocard (I am assuming a YP Railcard still needs a photocard), it can't be used by anybody else.
Even though those are the rules, doesn't mean the rules are right and indeed it always seems to be in the favour of the TOC not the company.
I have an annual season ticket, and could get on at an ungated station, and only realise when I arrive at my gated station that I have to buy a new ticket. Of course they should be able to check the database of most season tickets and you get a refund on the ticket you had to buy a couple of times, then you pay the fee.
I really don't see why something similar could not be done for railcards... oh yes of course because its only TOC friendly, not passenger friendly.
