710: How to inspire in-game hate in players.
A man walks into a tavern carefully carrying a sack. The sack occasionally twitches and mews. He sits down, politely asks for two pieces of toast - with butter. While they're coming, he pulls out a napkin and spreads it on the table/bar, then reaches into his sack and pulls out a kitten. He strokes the kitten. The toast arrives. He tickles the kitten under its chin, breaks its neck, and puts it between the pieces of toast.
