 Extra Reading (P.90) Where, when and how did the name “cocktail” originate? The story goes back to the time of the American War of Independence. It happened in the town of Winchester (温彻斯特), New York in a small public house. A young waitress named Betsy Flanagan made a new drink and she named it "Cocktail". This was because she used a feather pulled from the cock's tail to stir the mixture to make it even. Just at that time, a group of army officers were waiting at their table and as Betsy came up to them with the drink, one of the officers, a Frenchman, shouted in French, "Long Live Cocktail!" Thus people continue to call this drink a cocktail.
