One day someone will be hunched over on a sidewalk, dying of thirst, and a patrolling Nestle®-branded drone senses (using state-of-the-art machine learning "customer needs" technology) his predicament. The drone hovers there projecting a holo-ad about Nestles hot product "Nectar of Life" which is just water from the region's last remaining aquifer cut with brackish water from the coast. The ad ends with a map to the nearest vending machine and buzzes off for it's next engagement. The man, too weak to move, just sits there, nothing he can do except wait for another ad drone to come by.
