There are times when there is only one left of my favorite bread, so I take that one. There are enough people who don't care. The store staff can notice that people bought all the May 25 loaves they put out, so that only the May 11 breads are left on the shelf, and refrain from putting out any more May 25s (or newer) until the May 11s are gone. If that doesn't move the May 11s, as a last resort, they can sticker them 25% off rather than throwing them away.

The store has full control over their algorithm for avoiding waste, and full control over what they put onto the shelf. They have all the tools for solving the problem, even in the face of some shoppers going for the newest date.
