You didn't mention whether the first class was empty. If it was, then perhaps he could have allowed it. If, however, I had been a first class passenger, I would have fumed. The whole idea of the class, and why people pay the huge amount, is so that they are more or less guaranteed to avoid contact with hoi polloi and all that such contact involves. I can't afford first class (or won't afford it) but travelling second often involves unpleasant experiences (noise, smells and very occasionally, threats).
In 2008 I was travelling back to Leicester (where I lived then) from Manchester. I took a TPE service from Manchester to Sheffield which was packed in Standard and about a quarter full in First. People, including me, decided to sit in First but the guard was having none of it. Despite being a really hot day and people being packed in like sardines in Standard, he was happy to allow that to continue and charge anyone the appropriate upgrade if they sat in First.
I guess it was his call but common sense should have prevailed there. His customer service skills left a lot to be desired.
I get that First Class passengers have paid more for their fares, but Standard passengers have also paid a fare too. If the train is that overcrowded and the only seats available are more expensive, they should still be used. I'm glad that some guards do actually see that.
