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, higher quality meals, and is more convenient and social. Chefs duties include cooking, cleaning, ordering supplies, and distributing tasks among kitchen staff. Being a chef offers good pay, opportunities to meet people and learn skills, but also involves long hours, stress, injuries, and difficult customers.
