From Heinlein's "Door into Summer"

The following quote is from Robert Heinlein's Door into Summer:

I thanked him and left with a really warm feeling. Mr. Doughty reminded me of a paymaster I used to have in the Army. Paymasters come in only two sizes: one sort shows you where the book says that you can't have what you've got coming to you; the second sort digs through the book until he finds a paragraph that lets you have what you need even if you don't rate it. (p. 85)

My new work place seems to have a few too many paymasters of the former kind...

(Incidentally, while Door into Summer is an enjoyable bit of fluff, it really doesn't compare to Heinlein's The Moon is a Harsh Mistress which I rate as possibly the best sci-fi book I've ever read.)
