It does sound strange to me. I wouldn't consider myself as someone knowing how to cook, but I mean, there's stuff like eggs, pasta, or sausages that you literally just stick into a pot of water and boil it for N minutes (where N is right there on the packaging even). And you wouldn't do that in a microwave oven.
Super valuable houses where nobody ever cooked. He said the only thing heβd ever be called to service was the microwave and the fridge.
But 10 years in, gotta refresh the house!
