Well worth several looks Eddy because of the links down at the end of the scroll. A good example of "the baker's dozen- thirteen for the price of twelve- and "lagniappe."
Definition by American Heritage Dictionary:Lagniappe derives from New World Spanish la ñapa, “the gift,†and ultimately from Quechua yapay, “to give more.†The word came into the rich Creole dialect mixture of New Orleans and there acquired a French spelling. It is still used in the Gulf states, especially in southern Louisiana, to denote a bonus a shopkeeper might add to a purchase. By extension, it can mean “an extra or unexpected gift or benefit.â€
