Why oh why won't the rail networks enforce cl dividing carriages?

I mean i had to go into London the other day (roads to busy to take the Rolls) so i booked a first cl ticket with Virgin Rail, you can imagine my horror when i found myself sharing the compartment with a bloody oik who was middle cl at best but could even have been working cl. I am as into equality as the next man but when one has to share ones quarters with riff raff then surely the bally country has gone to the dogs, next the great unwashed will be farting in the palaces of the mighty........what should we do about this damned state of affairs
