Well I got to be Sherlock Holmes / Chef Ramsay at my local gas station last night.
So ....
There was this chocolate milk that people were complaining about. Dated the 19th of December.
Having worked in "The Industry" for 20 fucking goddamn years, I offered my assistance. Mostly because the girl playing manager is ... fucking hot. If I were a younger man, I would be intimidated.
I told her that all the additives to chocolate milk can cover the taste of sour / bad milk, and that it's probably mislabeled, and that it's probably due to truck driver shortage, and it's probably best to just throw it out.
"So there have been complaints. And your gentleman friend here says it tastes like chocolate. And it's not out of date. But multiple folks have complained about it tasting sour. Hmm."
Then, I took a sip of it. It was rancid as shit. This was shit-shit. Holy goddamn hell it was shit. Even by gas station standards, it was shit. It tasted like milk that came out of a garbage can.
First, don't drink chocolate milk - you're not a tween anymore.
Also, don't believe the dates printed on the carton - trust your taste buds. It cuts both ways. The date is meaningless.
Plus, just don't drink cow milk. Have you ever looked that shit up? There is a reason it's pasteurized.
If you simply have to drink animal milk, try your local goat milk. Yeah, goats are dicks, but cows hate you even more.
