The World's Most Accurate Delivery Without GPS

Can you imagine a delivery service that works flawlessly without GPS, robots, computers and any other modern technologies? Meet the Dabbawalas - the delivery service in Mumbai, India, that’s been operating for around 130 years already. These guys deliver home- and restaurant-cooked meals and they’re one of the oldest food delivery services in the world. With no advanced technology, they somehow manage to deliver up to 200,000 lunches a day, and they do that in less than three hours. They’ve invented their special code system, which helps them work with almost zero mistakes.
