Andy is an AI automaton, and his job was to assist his human. His human has died, and now Andy is left to his own means. Andy, being an AI automaton knows what he knows, what he was taught, and nothing else. So Andy is rather shorthanded in particular matters that would be considered common sense to any of us. As Andy navigates his environment he discovers that it's not only his human that has died, but possibly all other humans. At least all humans nearby. Andy makes a visit to a nearby convenience store to get a Coke, which his human did every day, but the machine appears to be broken. There is electricity inside the convenience store, but the soda machine doesn't work. Andy is disappointed.
