A person who mixes and serves drinks at a bar.
A bartender is a person whose job is mixing and serving drinks at a bar or restaurant. Bartenders work behind the bar counter, taking orders from customers, pouring drinks with precision, and sometimes creating elaborate mixed drinks that require special techniques.
You might see bartenders in restaurants, hotels, cruise ships, or at special events like weddings. Some bartenders learn fancy moves called flair bartending, juggling bottles and shakers to entertain customers while they work.
