Final answer:
Zack should immediately report the threat to his supervisor, store security, and local law enforcement. He should then follow the store's emergency protocols, potentially including an evacuation, while ensuring customer safety and preventing panic.
Step-by-step explanation:
If Zack, a store associate, receives an anonymous call threatening to crash a plane at a Walmart store in the next 10 minutes, he should immediately take this threat seriously and act quickly. His first step should be to inform his supervisor or the store manager about the threat. They, in turn, should swiftly contact the store's security personnel and local law enforcement authorities.
While waiting for authorities to arrive, Zack and other staff should calmly initiate the store's emergency protocol, which may include an evacuation plan. It is crucial for Zack to stay calm and avoid creating panic among the customers. If Zack or any other staff member is trained in such procedures, they should guide customers to exit the building in an orderly and efficient manner, while ensuring everyone's safety to the best of their abilities.
Zack should never ignore such a threat, and it's important to remember that every minute counts. Taking swift and decisive action could potentially save lives and prevent a disaster.
