Somewhere between Macclesfield and Birmingham if I remember correctly. This was all about 5 months ago.
The conversation was more or less along the lines of (heavily paraphrased):
Inspector: You don't have a valid ticket.
Me: Yes I do, I bought the ticket I was told to buy after explaining which routes I intended to take.
Inspector: But its the wrong route.
Me: But I make this journey on a regular basis using this same ticket and it was inspected every time without a problem.
Inspector: The previous inspectors probably didn't check the route.
Me: I've done everything I reasonable can to buy the correct ticket. So whilst I understand the problem I don't think its my problem I was sold the wrong ticket.
Inspector: Well I'll give you an excess, and take your name and address. We will write a letter to you.
Me: I don't want a letter from you.
Inspector: Its nothing to worry about. It will help us to get the money for the ticket from the 'via London' operator.
Basically I asserted throughout the entire conversation that I had done everything I reasonable could to purchase the correct ticket, and that as far I as know I had the correct ticket. When the conversation ended I was left under the strong impression that the matter had been resolved.
