I worked at a place like that once. About four years ago.

[He's honestly done a lot of different work just to stay on his feet after running away from home. Some things he's not proud of. But working there? He's not ashamed he did it.]

A servant is someone assigned to do tasks to take care of a building and the people they work for. A server is someone hired by a food or drink establishment to bring the food to the customers as well as to find out what they'd like to eat.
