Was OC PMS at Wittering, having recently left DIOT, when Bobby Robson visited to do some sort of "fact finding" tour. I had arranged all the usual things and, as it was a short notice visit, met him at the guardroom to give him a copy of the Visit Instruction.
He took one look at it and then said "Jump in the car Al, you can show me what really happens and bugger the VI".
I did a quick phone call to the boss to tell him what was up and that I would be unavailable for most of the rest of the day and Bobby Robson got the real story which he wouldn't otherwise have got.
Top bloke.
