It's been told that in the 19th century, pineapple was a special and unique fruit for the aristocrats of the time. Upon arrival to the plantation for a visit, guests were offered a slice of pineapple as refreshment. However, if the guests were to find a whole pineapple on a breakfast tray upon waking up in the morning, it's a hint from the host/hostess that they have been extending their stay too long and it's about time for them to vacate the property... The wealthy folks have their subtle way of saying good-bye, no?
