A cashier is a person whose job is to handle money in a store or restaurant. When you buy something at a grocery store, the cashier scans your items, tells you the total cost, takes your payment (whether cash, card, or digital), and gives you change if needed. The cashier may also bag your purchases or help you load them.

A cashier works with the cash register, the machine that stores money and records sales. A cashier needs to be good with numbers, pay attention to detail, and work quickly when the store gets busy. They're often the last person you interact with at a store, so a friendly cashier can make your shopping experience pleasant.

In some places, self-checkout machines are replacing human cashiers for simple purchases, but many stores still employ cashiers because they can solve problems, answer questions, and provide customer service that machines can't match. The verb form to cashier means something completely different: to dismiss someone from a job in disgrace, though you'll rarely hear this usage today.
