I’m from 'Murica and I’ve never seen milk like that before. Here, they say it’s okay to drink the milk up to ten days after the date printed on it.
And my family of three buys milk in liter bottles and we seldom use it, we usually end up pitching the leftovers out after they’ve sat for a month or so.
I think you’re right that milk (everyone I know has milk) and dehydrated milk should be much more common. When I was a kid we were on welfare and all we had was powdered milk, which was pretty much the standard in our low-income area. That was 20 years ago, though.
Also, fun fact, I sometimes recognize Russian words and your picture made me remember how to say Milk in Russian. So, thanks for that.
