"The British call our 'lazy Susan' a dumbwaiter, which the revolving servitor was called in America until relatively recently. It is said that the first use of the term dates back to about 75 years ago when the device was named after some servant it replaced, Susan being a common name for servants at the time. But the earliest quotation that has been found for lazy Susan is in 1934, and it could be the creation of some unheralded advertising copywriter. Therefore, 'lazy' may not mean a lazy servant at all, referring instead to a hostess too lazy to pass the snacks around, or to the ease with which guests can rotate the device on the spindle and bring the sections containing different foods directly in front of them."
