- In "Nightflyers", the titular ship is crewed by one man, Royd Eris. At the beginning of the story, the people taking passage on the Nightflyer all meet in the lounge for a meal shortly after they arrive. When they come into the room, the food is hot and waiting there for them. But Royd Eris is confined to the other side of the ship! There's no door between his side and the other! And if there is no other crew (and no androids were mentioned at any point in the story), who prepared the meal?!
