I must say I had him sussed as a fake early on when he was presented to us by one of our airport clients.
He seemed too good to be true and claimed that there were many airports that, following talks with him, had agreed to buy our consultancy and software services. When we later contacted them many had never heard of him.
However, the airport that put us in touch with him claimed he was for real and we took him out to Florida to meet one of our other airport clients who was trying to attract a trans-atlantic service.
Of course nothing came of his airline and the only thing that came out of the trip was an enormous hotel bill which he ran up invloving all manner of room-service, telephone and laundry items!
Interestingly on the flight out there he took an interest in a mother travelling with a small child - at this point he informed me he was a child phsycologist. This struck me as a little odd but I thought nothing more of it.
On our last night in Florida we went out for some drinks with a friend of his. We made a stop at a petrol station; Robertson was sat in the front seat and I was behind him. His window was open and he thought he had not closed his door properly. He (rather foolishly) tugged on the sill and at the same time (not seeing what he was doing) I got into the back and slammed the door straight onto his middle finger. The BMW 5-series door made an absolute mess of his finger (they are pretty solid things!) and I felt absolutely awful about what I had done - even though it was a complete accident. I must say I feel slightly less guilty now!
Good riddence to a vile individual - I hope the sentence is long.
