Most bartenders take drink orders, serve drinks, and collect money for drinks. In restaurants bartenders fill drink orders placed by the diners, but the drinks are usually served by waiters. Bartenders may have additional duties.
Sometimes they arrange bottles and barware, wash glasses, and clean the bar. Bartenders also remove empty bottles and trash and replace empty beer kegs. In large bars and restaurants they may be assisted by a bartender helper.
Bar Restaurants may ask bar tenders to take food orders. You may also have to wait tables.
