Some people say there's no such thing as a free lunch, but that's only true if you don't like poached eggs. It's unclear if the yolkers are available on a donation-based thing (perhaps as a free incentive for parking in the lot?), or maybe with a "take an egg, leave an egg" policy.
While the origin/intent of the lonely box of eggs is lost to the vagaries of history, there's still time to pick up yours. Grow your own chickens! Hard-boil the sucker! Just make sure you do it soon — they've been out there at least since yesterday morning, and offers like this won't last long*.
