Why do people buy milk and bread? Who eats milk and bread?
In the South, when cold weather comes, the weather folks are notorious for pushing milk sandwiches. Even one flake of sneaux, or a hint that ice might form, makes milk and bread fly off the shelves.
Pasty white boys like me. LOL I have no idea why people do that, but yes, they do it. I grew up in the Appalachian hills, and when a major snowstorm was forecast, the bread and milk would disappear from the stores. Me? Bottled water, generous amounts of beer, canned meat, check the level of various condiments, and just plan on a 72 hour power disruption. Back home, we'd make sure we had firewood. No worries about milk or any of that - we'd stick it outside in the snow to keep it cold. Down here in the Gulf region, I don't care if I drink warm beer and eat corned beef out of a tin with a key opener on it. Keep plenty of Slim Jims and jerky in the cupboard. A couple tanks of propane and ice to keep the steaks and chicken cold for a few days. I've got a fireplace and a wood stove, if I need to cook. I'll be fine. I've been through storms of hellfire and brimstone, and it doesn't ruffle my feathers. Your average Generation Zero soy boys would soil their onesies if they didn't have a working microwave and Internet access for a few hours. Piffle.
Lots of people have children, and some who don’t still like milk. Important macaroni and cheese ingredient, too!
As to bread, sandwiches, no cooking necessary.
Milk samitches!
