“When the red, white and blue concoction was shoved across to him he pulled a red handkerchief out of his pocket, attached it to his cane and held it over his head with one hand, while with the other he tilted the glass until the cocktail trickled down his throat. “What's the game?” asked the bartender.“No game at all,” said the big man. “It's strictly according to naval regulations. Red flag hoisted to signal that I am taking ammunition aboard, that's all” and with a cheer for the red, white and blue, he wandered out.”
