The hospitality industry consists of any establishments that serve food or drinks for a fee. It includes chefs, waiters, bar tenders and cleaners. While cooking at home can save money, eating out allows for greater variety of higher quality meals and is more convenient and social. Chefs duties involve cooking, cleaning, ordering supplies and distributing tasks. Being a chef offers good pay, opportunities to meet people and learn skills, but it also involves long hours, stress, injuries and difficult customers.
