Final answer:
A manager not exercising reasonable care in alcohol service is considered negligent, which can result in legal issues and harm the business's reputation.
Step-by-step explanation:
Negligent managers are those who supervise alcohol service and do not take reasonable precautions. In the corporate world, management must make sure that all organizational policies and service regulations are followed, especially when it comes to establishments that sell alcohol, in order to avoid responsibility and avert problems.
Managers are expected to train staff appropriately, monitor service to prevent overconsumption, and ensure that only legal-aged customers are being served. Failing to do so can lead to legal consequences and harm to both patrons and the business's reputation.
