Am I Missing Something?
They gave him a one million pound bank note. If he keeps it intact for a month, he gets any job he wants. Wow. He even assumes this job will be worth 500 pounds a year. Why not just take the one million pound bank note (which would be equivalent to 2 millenia wages by his estimation) and cash it in? It says it's payable to the bearer, just like cash. But rather than have a million pounds, he'll go through hell to achieve a 500 pound-a-year job.
Further, carrying that sucker around no one had the idea to steal it (I mean steal it and keep it not steal it and hide it for an idiotic reason)?
Incidentally, after it's all said and done, I know Peck's character is better off, but I don't remember those two old coots giving him any job at all. Just a thanks for settling the bet and bye.
