"Sambos" was the name of a U.S. chain of breakfast houses, similar to IHOP. Once ubiquitous, only
one store remains - the original restaurant in Santa Barbara, California, from which the chain sprang. When the owners discovered a book entitled "Little Black Sambo" written by Hellen Bartrum in 1899, in which an East-Indian
child is chased in a circle by a tiger until the tiger turns into
butter, they decided it was a perfect match, and Sambos restaurants thereafter featured conspicuously mounted placards telling the story, and ultimately relating the
butter to the blobs of whipped
butter served on Sambo's pancakes.
Whether the chain closed because of concerns relating to "political correctness" is unknown to this author.
