A food sampler is a retail food demonstrator who provides a taste of new or featured products to interested customers. The job duties of a food sampler are to set up booths in retail stores, demonstrate how to cook using a particular product, and provide free taste samples to passing shoppers. Other responsibilities are to set up, clean, and break down a sample station in retail stores and promote a brand product to encourage sales. A food sampler needs good interpersonal skills so that customers find them approachable and buy the products. The qualifications you need to become a food sampler are a high school diploma and customer service or sales experience.
