Familiarity with point-of-sale (POS) systems, cash handling procedures, and, in some locations, lottery or age-restricted sales regulations is essential. Exceptional customer service, reliability, and the ability to remain calm under pressure are important soft skills. These abilities are vital for maintaining a smooth workflow, accurate transactions, and a positive customer experience in a busy retail environment.
