Curious customer; but knows his business.

He's not much to look at; but he's a devil to work, and he's a born manager.

What I mean is, that he sees what a man's worth, in the--er--twinkling of an eye.

And here's a tip for you: never argue with him; don't contradict him; just let him have his say and keep your mouth shut.

If he says the moon's made of green cheese--ask him for a biscuit to eat with it.
