You did well to pass in Winchmore Hill if it was anytime recently! Those examiners are bastards! (I should know, I'm a driving instructor!). WH's closed now and moved to Enfield by the Innova Business Park.
Bury St Edmunds at the tender age of 27, a long time ago. My 3 point turn was interrupted by a flock of sheep that had escaped from the market. I had to park the car and help the examiner and the stockman to shepherd them back into the market. Did not have to complete the 3 point turn.
My Driving Instructor was very 'old school', he used to wrap me over the knuckles with a wooden ruler if I left my hand on the gear lever for too long. He also gave me the bollocking of my life when I argued with him during a mock test, it worked, I passed first time !
