Final answer:
When encountering a broken board in a kitchen's server, the Maintenance Staff should be contacted as they are responsible for handling repairs and equipment issues, not the Head Chef, IT Support, or Server Manager.
Step-by-step explanation:
If you come across a server with a broken board in the kitchen, the most appropriate person to reach out to would be the Maintenance Staff. The Head Chef is responsible for food preparation and kitchen operations, while IT Support deals with technical issues related to computers and networks. The Server Manager may be in charge of the dining room staff or servers, but not for fixing broken equipment. Therefore, Maintenance Staff are typically responsible for repairs and would be the correct choice to address such a physical issue in the kitchen.
