I find being convenient with the truth is good, who's to know that my watch isn't 2 minutes fast!
Won't help you that much, given that customer services will generally check the records and make sure that the train in question really was as late as you claim. That's one of the reasons why conductors (at least when they're using the Zifa equipment to mark tickets, which they're supposed to) stamp the train reporting number on there as well.
Cant remember the last time a
FGW▸ TM▸ actually stamped my ticket. If you are lucky you may get a scribble
Then there was the day THREE arriva guards stamped the same ticket! Well actually one was
FTP▸ from liverpool to manchester then one from manc to crewe and after another full ticket check from crewe to ludlow
Interestingly enough - Lud to liverpool via manchester is not technically a valid route but not one guard, TM, platform gestapo or anyone has ever picked me up on it. And the only reason I go that way is because there are two stations I hate in this world - Shrewsbury and Crewe - I'll do anything to avoid changing at them
