Summer jobs for a waiter involve the same duties as year-round positions but typically only last through the summer season. As a server at a restaurant or bar, you take and deliver customer food and beverage orders and complete various tasks such as polishing silverware, folding napkins, and restocking condiments. Your responsibilities vary based on the type of restaurant you work in, but you need to familiarize yourself with all the menu items, make recommendations, and ensure customer satisfaction. You also process cash and credit card transactions and check customer IDs before serving alcoholic beverages.
