What should you do after the robber leaves the store?

Calling 911 immediately after a robbery is the most appropriate action to take. This allows for the swift response of law enforcement to apprehend the suspect and ensure the safety of everyone in the area. Notifying the police is critical for documenting the crime and starting an investigation to recover any stolen property or collect evidence.

Taking other actions, such as leaving the store open for customers or continuing business as usual, could put others at risk and fail to address the immediate safety concerns that arise from a robbery. Checking the security cameras, while useful in assessing the event later, does not provide immediate assistance or alert authorities. It's essential to prioritize safety and security in such situations.
