Sounds like a right twat. However, bad manners isn't the speciality of the young types mentioned in your nom. I held open a door for two middle class women in their 30s at the gym last week and they breezed through chatting to each other and not one of them said thankyou. I shouted out to them "Thats okay, you don't need to say thankyou you pair of middle class retards". The look on their faces cheered me no ends. I certainly won't offer to sell them any lucky heather!
