“But there’s others that come every night, or anyway four or five nights out of the week. They’re specialists, and only foller one weapon, or perhaps two, and they pretend to know more about those than them that use them, which perhaps some do. After your victory, sieur, two or three will want to buy you a round. If you let them, they’ll tell you what you did wrong and what the other man did wrong, but you’ll find they don’t agree.”
