Why must the back door remain unblocked by trash or stock during restaurant operation hours?

The correct answer emphasizes the importance of maintaining clear access to the back door as an emergency exit. In restaurant operations, safety is a top priority, and having unobstructed emergency exits is crucial in case of unforeseen events, such as a fire or other emergency situations. Keeping the back door accessible ensures that all staff and patrons can quickly and safely exit the building if necessary.

This requirement aligns with safety regulations and best practices within the food service industry. Ensuring that exits are clear not only adheres to legal obligations but also protects the well-being of everyone in the establishment. The focus on emergency preparedness is a key part of running a safe and compliant business.
