Scotrail not accommodating delays on advance tickets
I am travelling London to Inverurie today on three advance tickets (London to Durham, Durham to Edinburgh and Edinburgh to Inverurie). My first train from London was terminated at York and the next was 40 mins late so I missed the 11.30 from Edinburgh to Aberdeen I was booked on. The guard on...

I would like to see the system changed so that commission is not paid to Guards who mis-sell tickets, either due to refusal to accept a valid ticket or due to selling a more expensive ticket than the lowest priced valid ticket.
If it's not possible to prevent the issuing of it, then it should later be docked from their pay at a later date.
I would also like to see more robust safeguards in place to detect and prevent such instances, including mystery shopping.
And if such instances continue and the industry isn't able to put sufficient measures in place, then consideration should be given to abolishing commission entirely.
