What is the difference between waiter and back waiter?

A waiter is responsible for directly serving food and drinks to customers at a table, taking orders, and providing overall customer service. In contrast, a back waiter, often referred to as a food runner or assistant, supports the waiter by delivering food from the kitchen to the table, refilling drinks, and ensuring that the dining area is stocked and clean. The back waiter typically has less direct interaction with customers and focuses more on the behind-the-scenes operations to assist the front-of-house staff.
