I do wonder about the whole parts-compatibility issue. There’s a tendency when you’re constructing an electronic device today to standardize on common hardware and interfaces as much as possible, because it makes manufacturing cheaper. I would have expected the male and female humanoid-hotelier-bots, at minimum, to be distinguished only by cosmetics and programming, not functional hardware. I suppose the parts from the bots in the robot graveyard could have been damaged by improper storage, but still . . .

(Also, I was suspicious of that “horse” from the beginning, because equine facial marking Just Don’t Look Like That.)
