"Only upstarts and parvenus shout to the whole tavern: “Champagne!” But every self-respecting person should use to say “wine.” And everyone around you should immediately understand that since you say wine, you mean champagne and not anything else. So in a restaurant, never shout: “Champagne!” Order to the waiter in a low voice, but impressively: “Be so kind as to bring me some wine.” He will understand. Rest assured. He will bring what you need."
