I don't care for them because I don't like the 'cor blimey' kind of London culture.
I come from the part of London that many east end folk moved out to (Chingford, Walthamstow, Leyton, Ilford - all round there) after the war and if you come from that working class culture everyone thinks you like nothing more than a knees up and a sing song along with a bowl of jellied eels on a Saturdau night. I once met a man who was totally shocked to hear me speak with some knowledge about Mahler's fifth symphony. 'Fancy you knowing about Mahler' were his exact words!
