Sharp as Coleman’s Mustard

Jeremiah Colman was once asked to sum up the secret of his success and how he made a fortune out of such a humble thing as mustard. His reply was that he made his money from the mustard that people left on the sides of their plate. Now as a young child I was confused by this and had visions of Mr Coleman going round and scraping the remains off peoples’ plates and reselling it. Ah, bless.Instead
