I was in the middle of making dinner when this happened. I’m grateful I poured it into a measuring cup first. Thankfully I don’t live too far from another source.
I remember milk staying good almost a week past its expiration date when I was a kid. Boy have the times changed.
It’s not a dealer’s issue or has anything to do with changing times. Everyone will or already has had that experience at least once. You’re just too inexperienced. There are many reasons why milk can go sour, as we call it here. Most depend on how you as a consumer handle it. Some are just bad luck. For example, if there was a thunderstorm, it’s more likely to turn into an ugly buttermilk mess. Don’t blame Walmart or the milk, because you can’t be sure if it wasn’t your fault.
Quite a lot of assumptions you’re making. I’m probably older than you.
