It's 10:30 a.m. and a group of office workers are desperate for a pick-me-up. One of them reaches for a KitKat bar, the crunchy chocolate treat made by international food and beverage company Nestlé S.A. He opens the package. Instead of chocolate, he breaks off a hairy finger of an orangutan. He takes a bite; blood spurts on the computer keyboard and runs down his chin. He casually wipes it away with his sleeve. His co-workers look horrified.
