I must say that I do enjoy arms deals.
Why, I am not too sure, but think that it may be something to do with the whole cut and thrust of the thing.
Yours truly: Well, I am not sure we need 30 Stealth Bombers at a cost of $530 mil. Maybe only 2, ok?
Seller (US): Now, we only sell in bulk, I am sure you understand.
YT: Ok, Ok. How about 10 at 2 million US?
S (US): Hmm, tempting, but lets talk about 15 at $600 mil?
S (US): Each.
YT: Of course. But then I would like en suite loos for each room in the villa in the south of France.
S (US): Agreed.
YT: Oh, and I want a motorised garage door at the villa. I have never opened a garage door manually myself and I have no intention of starting any time soon.
S (US): Done.
And that is how one gets what one wants.
