Arthur Morrison,
The Red Triangle — The Affair of Samuel's Diamonds
(1903)
“ When I sell to make a profit, perhaps for somebody else, I don't want that somebody to know my customer, else he sells direct and I lose my profit—fery natural. See?" "Of course, I understand. It's a point of business among you gentlemen to keep your own customers to yourselves. And often, no doubt, diamonds pass through several hands before reaching the eventual customer, leaving a profit in each." "Always, Mr. Hewitt—always, you might say. Well, you see, Denson sends down that his customer is in, and I come up. Denson comes out from the inner office, takes my case, and I wait in there." ”
