This is way more an issue than some realize. A repairman I used to know would always have great deals on amazing kitchen gear. It was always 5-10 years out of date but barely used (Viking oven where the burners had been used a bit, but the oven still had all the plastic bags and manuals in it).
Super valuable houses where nobody ever cooked. He said the only thing he’d ever be called to service was the microwave and the fridge.
But 10 years in, gotta refresh the house!
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.
Cooking — as in being able to make any set of common ingredients tasty, quickly, with few dishes to wash, and without looking up recipes each time — is the skill you need before you can “unlock” supermarkets. If I was still 19 and a new supermarket showed up, I would know f— all to do except browse the frozen section.
