Soups usually get things that are not-as-fresh because they get simmered all day anyway- no one is gonna notice if the the carrots were getting flacid or if the protein is dried out from being cooked and not served.
They make the soup fresh daily- just in the morning. and they keep it hot so as to get it out quickly. The ingredients they use, though “fresh” are not the freshest in their pantry, if that makes sense. It’s the left over trimmings that get chopped up so as to hide it (this is actually a good thing. It reduces waste.)
