When billionaire Horatio Magellan Crunch retired from the loud, stressful, high-stakes grain investment industry, he never wanted to interact with the common folk again. Over the next years, he gradually fired his extensive staff and replaced them with machines built from his own possessions, growing too stingy to pay for other materials. Soon, he could go for a morning stroll, hang up his umbrella in his hunting lodge, warm the building, brew his tea, and pour his daily bowl of cereal without ever speaking to another person. The true extent of his morning-automating machine was only discovered after his tragic death last week, when he became yet another victim of the infamous cereal killer of southern Tucson.
