" Fred put vinegar on things, and no man who did that ate at Wolfe’s table. Fred did it back in 1932, calling for vinegar and stirring it into brown roux for a squab. Nothing had been said, Wolfe regarding it as immoral to interfere with anybody’s meal until it was down and the digestive processes completed, but the next morning he had fired Fred and kept him fired for over a month. "
