D'oh!

Last week I had to go to London for a half day assessment with a view to getting a job with a Government Department. Because the assessment started at 8:00am I had to travel down the night before and book overnight accommodation...in London.
Now I'm scared of London, don't mind admitting it. I have a real hick from the sticks fear of the big city, a quasi Dickensian image of a fogbound London, horse shit in the gutters, and Hansom cabs plying their trade while troops of quick fingered pickpockets prey on the newly arrived yokels.
OK, that's perhaps a bit strong. I don't even know if I can claim to be a yokel or a hick when I come from Liverpool but you take my point. I was afeared of the dreaded underground, finding the place i neede to be, finding my hotel-oh I was in a right state. Imagine my delight when the tube station was on the same road as the assessment centre which was in turn within eyesight of my hotel.
Result! Apart from the shock of being charged £3.25 for a pint of Bombardier bitter I was well pleased.
The next morning I turn up at the assessment with everything except photo ID. Despite there being a name badge for me and my having copies of all the forms they had emailed me and despite my argument that who else could I possibly be? they couldn't 'do ' me.
Ever had to kill six and three quarter hours in London when you feel like a dope and just want the world to swallow you up?
It was an omen.
My next interview is with a firm that is ten minutes walk from my house.
That's more like it.
