We'll see this come into play in about six years or so when John stops acting like a sitcom mutant groaning about the bills and agrees to put an add-on to the house to give everyone more room. As one could expect from the "John remodels the kitchen in such a way as to maximize the inconvenience Elly" arc from about two years from now, we're going to have the contractors speak either hick-speak or wit'an exAGGerATed acCENT to remind us that the lower ranks aren't as exalted as people like Elly. We're also going to have them balk at her super-reasonable and not at all insane requests as well as having them make her life harder because reasons.
The interesting thing about all of this is that she claims to be friends with the real person despite making him into a caricature. She seems to have a lot of people like that in her life.
