Liquor store jobs focus on sales and retail operations within a liquor store. Your job duties may depend on the size of the store. In large stories, a manager may manage operations, while a cashier handles transactions with customers and, if necessary, verifies that they can legally purchase alcohol. As a buyer, you obtain products from distributors and wholesalers, while inventory workers stock shelves and check inventory. In a small or independent liquor store, a manager may also buy from wholesalers, and a cashier may stock shelves, provide customer service, and fulfill other responsibilities.
