The couple who’d been up against the window weren’t there. Nobody human was. Robots, little low beige things that moved almost too fast to see, were vacuuming the floor, while three almost identical robot girls were arranging food on a long table. Classic anime robot babes, white china faces almost featureless. They’d built three big flower arrangements and now they were transferring food from carts to trays on the table. When the carts came in, rolling themselves to the table, the blur of beige parted just enough to let them through. Flowed around them like mechanical water, perfectly tight right-angle turns.
