That is exactly the point, Hadders. There would be time to resolve the issue. I fI am unable to collect tickets ahead of time, then I'd certainly leave more than 10 minutes at the station to do so, just in case something goes wrong and I need to get it sorted out.
Just like if I fly somewhere I leave in plenty of time to get to the airport to allow for something going wrong en route.
All this sad tale does is to remind me what can happen sometimes, and I wouldn't want to be in the same position as the OP found themselves.
