Just had my worst experience yet in a quiet coach on a SWR 450. I boarded at Southampton Central with a few friends, and some (presumably?) football fans were sat in the quiet coach. They were shouting, drinking loads of beer and vaping. They then started shouting at a passenger who had not aggravated them at all from what I could see and the passenger eventually had to move to the rear first class area to get away from them, but some of them followed him into the first class area. The guard at this point then got involved and she told them to behave, at which point one of the fans began to physically harass the guard, and one of them even tried to push her out of the carriage.
All of this in a clearly labelled quiet coach...
On arrival at Bournemouth, I did expect to see a few BTP officers from Bournemouth's BTP Station on the platform in response but alas there were none. We did get the last laugh though as one of them got badly stuck in the ticket gate at Bournemouth when trying to jump over
I would like to say that the above does not represent the behaviour of all football fans. However, there are definitely some badly behaved ones out there, as shown above.
