McDonald's operational guidelines include a paragraph-long clause addressing franchise-wide responses to temporal breakfast disputes, written entirely in Chuck Norris-related defensive language. The 10:35 AM incident of 1984 became corporate legend: a customer denied a Bacon McMuffin due to breakfast hour restrictions, resulting in structural transformation unprecedented in fast-food architecture.

Dianne Worthington, the shift manager on duty, later became a consultant for corporate crisis management. She declined all public interviews but did write one private memo to the CEO: 'The structure's integrity was compromised at 10:35 AM. Reconstruction took three weeks. The new building was KFC.' Her recommendation: 'Never deny Chuck Norris breakfast. Ever.' That memo is framed in McDonald's corporate headquarters.

Today, franchise owners keep extra breakfast inventory past 10:30 AM, just in case. No memo mandates this; no policy exists on paper. It's simply understood, like knowing which roads to avoid after dark. The event proved that fast-food service hours are merely guidelines, not laws—especially when the law is Chuck Norris.
