Final answer:
When giving change to a customer, cashiers are required to repeat the amount of change and count it back.
Step-by-step explanation:
This question is related to business and customer service.
In most countries, when giving change to a customer after a cash purchase, cashiers are required to repeat the amount of change to be returned and count the change back while giving it to the customer. This practice helps ensure accuracy, provides transparency to the customer, and reduces the possibility of errors.
For example, if the customer's purchase total is $10.00 and they give the cashier $20.00, the cashier may say, 'Your change is $10.00' while placing two $5.00 bills in the customer's hand.
