A Köbes wears a blue apron and blue jacket and has a big leather belt with a leather purse. He serves beer and food to guests and replaces empty beer glasses with full ones until the customer either places a beermat on his glass to signal that he doesn't want any more, or until the customer asks to pay.
The word Köbes comes from the name Jakob in a local dialect.
