A bartender (also known as a barkeep, barman, barmaid, bar chef, tapster, mixologist, alcohol server, flairman or an alcohol chef) is a person who formulates and serves alcoholic or soft drink beverages behind the bar, usually in a licensed establishment. Bartenders also usually maintain the supplies and inventory for the bar. A bartender can generally mix classic cocktails such as a Cosmopolitan, Manhattan, Old Fashioned, and Mojito.
