Railcard discounst not being avaailble at a ticket office unless the railcard and its owner are both present. This meant that I was unable to buy a ticket in advancefor my 85 year old grandmother, who thus had to make a special trip into town for the purpose. (THis was in 1981, when online purcahses were not possible. Bizarrely, the rule still applies to tickest bought at ticket offices, although telesales and online sales don't require a railcard to be present (or even exist at the time of purchase - I bought an advance ticket with an over-60 discount when I was still 59).
To offer an alternative but similar scenario; you wouldn't expect a supermarket checkout operator to take your word for it if you stated that you had a clubcard without showing evidence of it, so why is it wrong that ticket offices require evidence of the railcard before applying the discount?
Perhaps the railway can make things difficult for passengers, but equally some passengers take the railway for granted and can be rude to staff, I would guess more so than in other retail/transport industries, so it works both ways.
