Not a dispute as such, more just a question out of idle curiosity. I travel through London Bridge most days changing from a Southern service to the tube via the new low-level concourse. There are always a lot of Southeastern staff at the gatelines, many presumably RPIs, but never anyone from Southern. This morning a young lady left the Southern train I was on, went down the stairs in front of me and headed straight to the Excess Fares window where she was met by a Southeastern employee. I’ve no idea what was said but she handed him a piece of paper so presumably everything was above board, but it does raise the question as to whether an RPI from Southeastern has any authority to question a Southern passenger. If not, isn’t unfair that Southern passengers could conceivably get away with fare dodging as there are never any Southern RPIs there? Not anything I would ever condone of course, I have a Travelcard and believe in paying for the service I receive (and claiming Delay Repay when I don’t!)
