You can't be that desperate to sell your product that you push the date back over and over again. Just eat the couple bucks and hike the price up on La Croix. The white people will pay upwards of ten dollars a can. That's where you'll get your money. I have a feeling the workers just kept smelling this day after day. If it smelled OK then they'd put a new sticker on it. Once it smelled bad, time to toss it or turn it into the store's chicken salad.
There are some horrifying things that go down in some grocery stores. It starts to make you wonder if you just should avoid eating all together. Maybe just start a cricket farm where you can grind them into protein bars and live off that. Actually, I'll take my chances with the chicken salad.
