What does a look-out do during a robbery?

During a robbery, a look-out is responsible for monitoring the surroundings to ensure that no one, such as law enforcement or bystanders, approaches the scene. They typically communicate with the robbers, alerting them to any potential threats or changes in the environment. The look-out plays a crucial role in helping the robbers execute their plan without interruption or detection. Their vigilance is essential for the success and safety of the operation.
