Ironically I would say Shabby is just as posh as Ben,clearly from an upper middle class background,articulate.

Ben is the one who tries too hard to seem posh; always going on about his friends and parties.

Also Ben probably resents the fact that he went to uni,is 30+ and still nowhere with his 'media career' apart from reality TV,whereas Shabby is 20+ and already has acted in actual films and tv shows.
Poor bitter,fragile,jealous Ben.
