Bartenders fill drink orders either directly from patrons at the bar or through waiters and waitresses who place drink orders for dining room customers. They must know a wide range of drink recipes and be able to mix drinks accurately, quickly, and without waste. Bartenders typically do the following:

• Greet customers, inform them about daily specials, and give them menus
• Take drink orders from customers
• Pour wine and serve draft or bottled beer and other alcoholic or nonalcoholic drinks
• Mix drinks according to recipes
• Check identification of customers to ensure they are of legal drinking age
• Clean bars, tables, and work areas
• Operate cash registers, collect payments from customers, and return change
• Manage bar operation and order and maintain liquor and bar supplies.

Some establishments, especially busy establishments with many customers, use equipment that automatically measures, pours, and mixes drinks at the push of a button. Bartenders who use this equipment, however, still must work quickly to handle a large quantity of drink orders and be familiar with the ingredients for special drink requests. In some establishments they also may use carbonated beverage dispensers, cocktail shakers or accessories, commercial strainers, mist or trigger sprayers, and ice shaver machines.

In addition to mixing and serving drinks, bartenders stock and prepare garnishes for drinks and maintain an adequate supply of ice, glasses, and other bar supplies. They also may wash glassware and utensils, and serve food to customers who eat at the bar. They are usually responsible for ordering and maintaining an inventory of liquor, mixers, and other bar supplies.
