I recall the first time I did my theory test........ (misty smoke on the screen, dream sequence style)
Me "I'm here for my Theory Test"
Receptionist "Can I see your Driving License?"
Me "Urm....Driving license...........(checks pockets)........ can I bring it later...?"
Receptionist "Sorry, No."
Me "*****, ****, *****, *****"
and so I had to rebook, and waste whatever the fee was at the time.
Did pass it one the first sitting, but second test. And I was in the day when you could do your practical before the theory, so for a couple or weeks I could proficiently drive one the road, but not without someone sat next to me, but they only had to make sure I knew which lane the horse would go round the roundabout, and what colour cats eyes go where, rather than watching for hazards.
