Final answer:
In the event of a tornado warning, the movie theater manager should immediately interrupt the show and guide the 500 attendees to a basement or interior room to ensure their safety. Emergency preparedness and the priority of human life over the continuation of a show or concerns about panic are crucial in such scenarios.
Step-by-step explanation:
When a tornado warning is issued, including your city, it is a serious matter that requires immediate action to ensure the safety of all individuals under your responsibility. As a manager of a movie theater with a show currently in session, the most appropriate action is to interrupt the show and guide the attendees to a safe location.
Emergency procedures dictate that you should not ignore the warning, and certainly not leave the venue for non-essential activities. Selecting a course of action that prioritizes the safety of the people in the building is paramount. Plan B, which involves interrupting the show and moving people to a secure area like the basement or an interior room without windows, is the recommended option. This action helps minimize the risk of injury from flying debris or the collapse of external walls.
The costs of boarding up windows and moving to a tornado shelter may seem high, and it may cause a disruption, but the costs of being unprepared can be significantly higher, including potential injuries or loss of life. If a tornado were to strike and you had taken appropriate action, attendees and staff would likely feel grateful and relieved that the threat was taken seriously and that their well-being was prioritized.
