Absolutely this. As a self-proclaimed yoghurt-weaving leftie I ought to object to First class on principle, but on the rare occasions I've used it I've enjoyed it. Does that make me a hypocrite or a human being?
My objection is the attitude expressed by some posters on here, that being able to afford first class means you're a better class of person and that we proles in standard should bow down and kiss the feet of the benevolent business people and gentry, whose wealth will one day trickle down to us...
Also the idea that standard class is filled with baying mobs of feral chavs who can smell wealth and want to eat the rich! We don't, despite the above paragraph which I promise is (partially) tongue-in-cheek!
