Cashiers typically do the following:
In some establishments, cashiers have to check the age of their customers when selling age-restricted products, such as alcohol and tobacco. Some cashiers may have duties not directly related to sales and customer service, such as mopping floors, taking out the trash, and other custodial tasks. Others may stock shelves or mark prices on items.
Cashiers use scanners, registers, or calculators to process payments and returns or exchanges of merchandise.
Although most jobs for cashiers have no specific education requirements, some employers prefer applicants with a high school diploma or equivalent. Cashiers should have a basic knowledge of mathematics, because they need to be able to make change and count the money in their registers.
