What are catering personnel?

Generally, you have the banquet manager who is responsible for organizing, timing, setting, servicing and staffing the event. Under the manager is a captain, who will be responsible for making sure the manager instructions are followed completely. Under the captain are the banquet servers. Where I work, we have a lead server who would oversee dinner service, a lead bartender, who oversees the setting up and running of the bar or bars and a kitchen lead, who will make sure the dirty plates make it to the dish pit and keep the coffee brewing.
