Oh that's a good point. My friend in NYC said her family (and some neighbors) have resorted to storing food on their fire escape. If she buys a week of groceries for her family all at once, they just don't have the refrigerator space for it, so fresh vegetables get kicked outside.
My parents had a fridge and a freezer and still stored things on the unheated sun porch with the windows open in the winter. And that was in a big house (though there were a lot of us too, so we needed it).
Also they got the cops called on them a lot when they used to dumpster dive.
My friends used to live in a nearby neighborhood where chickens and all outside animals were banned. They got fined for 3 hens behind a 6' fence. I grew up there. Neighboring city doesn't let veggie gardens in the front yard.
People live under all sorts of circumstances that makes grocery shopping a necessity. And it's not like there's anti-viral masks for symptomatic people to buy and wear. -_- Sometimes you just have to go to the grocery store.
The purchase might even look irresponsible. When I had Mono the only thing I could eat for three days was pizza rolls. G lives off of cucumber lime and orange flavored Gatorades when he's sick. D used to eat nothing but PB&Js when sick. People do what they gotta to get by.
