Another annoying thing we had to learn is that rich people who live in multi-million-dollar homes almost always complain about the price when we mention it. As if we would charge them more just because they life in a mansion. But we do not. Actually the price gets lower if you have a bigger house because you usually don't have 3 kitchens, just more bedrooms (and unused baths) that are done quicker.
And people with smaller homes and kids, both parents working, who can barely afford a professional house cleaner, they usually accept our prices. The world is unfair.
