As a food demonstrator, you showcase products to shoppers at a table or booth. A food demonstrator often works in grocery stores, answering customer questions, handing out food samples, and providing live demos of products. Your responsibilities include preparing food samples for people, promoting sales of a product or service, and sometimes distributing materials out to shoppers. Other duties include food preparation and sanitation, providing product coupons, training new demonstrators, and learning skills on the job. Usually, one of the qualifications for demonstrator roles is a high school diploma or GED certificate, but customer service or sales experience is helpful as well.
