In my last trip to South-Africa, a person was actually bitten by a snake. Because we are in a mining enviroment, they have snake wranglers to remove snakes from offices and stores or the mines. They have a fully equiped ambulance and also have several anti venoms. The snake was killed and the docter/snake wrangler identified is as not dangerous, so to wound was treated. But obviousely it gave us a bit of a scare. Especially because it was close to the restaurant.
