:P Did you actually buy it? I doubt very much that a FCC RPI could do anything about it (such as issue a PF) if Im honest, apart from alert management about the error.
No, I bought a Super...Off Peak TravelCard. My friend, however, did. And it opened all the gates!!
I got my ticket from the EastCoast machines. I checked and they DON'T sell Paddington tickets.
I have reported it but I doubt it will change.
Should add, wish I had though. I would have loved to argue the toss with a FCC RPI. Especially with my 'picture' as evidence. May go along on Sunday just for the heck of it. I'll wait all day until I see a RPI and then talk loudly about my 'trip on the tube'.
