Which of the following would be considered suspicious to observe while driving around the restaurant?

Observing unlocked doors and broken glass around the restaurant would raise immediate concerns about security and safety. Unlocked doors could indicate that the restaurant has not been properly secured, making it vulnerable to unauthorized access, theft, or other criminal activity. Additionally, broken glass is often a sign of vandalism or a recent break-in, which could indicate that the location has recently experienced a security breach or might be at risk for one in the future.

In a restaurant setting, especially one that operates late hours, maintaining a secure environment is crucial for both the safety of employees and customers and for the overall security of the establishment. If these conditions are noted, they would warrant further investigation or immediate action to ensure the safety and integrity of the restaurant.
