As it is a free-write, if looks ok, but in general or overall the story missing any convincing plot, Since the certral plot is revolving around salesman and his skills from the beginning it could have been better if there was some more explanation on how he had convinced them, if not both or at least one.

or you could keep asuspense till the end what exactly the assignment or the nature of the salesman's special skill that required him against all he learned till that point

Anyhow, thanks for story, it was a good sunday read
