I travel to London from Reading one or two days a week.  I pay the ^39.40 one day travel card rate and recently on coming home lept onto a very busy train (nothing new there) and stood between two first class carriages, knowing the standard would be packed and I'd be unlikely to move through the train without disturbing other passengers.  To my surpise I was told by the guard to move.  As I was standing between first class carriages I was in first class and if I stayed would have to pay a first class fare! I've stood there before and this has never happened to me.  Is this a new policy?  Is it another way that FGW^▸ (First Great Western) can charge me ^40 for a 25min jounrey and still treat me like some Victorian working class oik whom first class passengers should not have to look upon?  I'm annoyed, can anyone enlighten me?
