The Menu at "Chez Werewolf"

The rant continues: Why do the old-style humans (OSH) have to resort to cannibalism? Is there evidence to support the idea that the Masters don't need to eat? (so they don't need to raise chickens, so they don't need chicken medicine or chicken feed, so there's no more chickens et al for the OSH to eat) If the Masters do feed, perhaps it's very rarely (I could probably go a long way on a cheese sandwich if my body didn't have to fight cancer and heart disease and stuff). Thus the supply would be very hard to get. Maybe the food they eat is poisonous to OSH. If the Masters eat three squares a day of reg'ler ol' stuff, fine. We know that the OSH can't walk into Kaminski's Deli because : The Masters recognize OSH on sight OSH don't speak the language OSH don't have whatever it is that the Masters use instead of money. But I don't like the last idea because it begs the question: "Why don't the OSH just hijack the Oscar-Myer truck while en route to Kaminski's"? Your thoughts please, -WHG3
