Sorry. Yes. None of this applies to a real deli, this was a mass supermarket deli. Deli meats and cheeses don't move very quickly. When the cut edge started showing its age, store managers had us slice off the end so it looked fresh. We were told to ignore expiration dates. By we, high school students. Too young to understand how wrong that was. I quit when my manager took a stack of brand name frozen pizzas that had expired dates on the boxes, removed the pizzas, and told us rewrap and sell them with deli stickers. Salads in the cases were also recycled. The old was always scooped ontop of the new so it would move first. However, there was no tracking how long a salad was kept. On the plus side, hot foods were prepared daily and not kept over, so at least there's that. Now a warehouse like Costco has enough volume I am sure so things like this would not be an issue. But your local grocery store, not so much. And that would be my advice: keep an eye on the customers getting deli meats and cheese where you shop. If the deli is busy, great. If not, maybe don't chance it.
