Among the classes rich enough to employ servants, complaining about those same servants is a perennial thing. Even a valet or chauffeur who comes out of an elite training school and knows to stay at the margins of his or her employer’s consciousness, might still have small human quirks that irk that employer. So, machines may well prove preferable servants over humans.

I think complaining about the quircks of your servants may often be in the same category as complaining that your new designer handbag doesn't colour match well with as many of your dresses as you'd hoped.
