That is unusual. I’ve encountered a couple people like this. They also refuse get-togethers in people’s homes and potlucks. One said he would be willing to come to a potluck if he could inspect everyone’s kitchens first; he wasn’t joking! It’s a blend of germaphobia and social distrust, I suppose.

That said, if someone was grieving and they couldn’t handle more than receiving delivered takeout, I’d happily send it, just as I’d accommodate another dietary preference when preparing a real meal.

The person needs to never see a commercial kitchen from the inside, lest they starve
