Beverly Hill Squatters
When your client lives in a humungous mansion, then you probably think you struck babysitter gold. That would be the case with most people, but the OP had a fascinatingly creepy story about this fully furnished mansion. After going through the drawers and whatnot, they couldn’t find a thing!
Why were they snooping in the drawers? That’s what babysitters do, so get used to it. Anyway, even the refrigerator was completely barren, which understandably spooked the OP. The client simply told the nanny to order food, and that was that.
