It was, by all accounts, a very British incident.
When Cat Lee, from west Yorkshire, boarded her train from Skipton to London with a friend, she discovered two men sat in their reserved seats.
After asking them to move and explaining she suffered from a disability that made it difficult to stand, the men allegedly ignored her and carried on staring at their phones in the hope she'd just go away.
She did. To Facebook. Where a bit of the old 'public shaming' has brought Lee and her unchivalrous nemeses to the attention of the world.
"I'm sure their wives and mothers would be proud of them," posted Lee, alongside the obligatory hastily taken phone pic.
And that was that. But was it? Since then, one of the men has claimed Mrs Lee said she could not stand because she suffered from groin pain but did not claim to be disabled or appear distressed.
They added there had been an announcement on the train stating seat reservations were no longer valid – meaning the passengers were under no obligation to give up their seats.
Ah-ha! Right then! So there was more to it after all, and there are two sides to every story.
Except no, not really guys. If someone on public transport tells you they find it difficult to stand, you do the right thing and take the hit. It's a free shot at being a good person. Take it next time.
