What must be ensured regarding the safe after each use?

Locking the safe immediately after each use is essential for maintaining the security of cash and sensitive information. When the safe is locked promptly, it protects the contents from potential theft or unauthorized access. This practice helps prevent any financial loss or discrepancies that could arise from leaving the safe unsecured.

In a fast-paced environment like Panda Express, where cash transactions occur frequently, ensuring the safe is consistently locked after use becomes a critical aspect of operational protocol. It fosters an environment of accountability and trust among team members, as everyone understands the importance of safeguarding the restaurant's assets.

While other options may seem practical in terms of convenience or accessibility, they would compromise the security measures necessary to protect the establishment's finances and sensitive data.
