What should a cashier check before accepting a coupon?

A cashier should check the expiration date and terms of the coupon before accepting it because these elements determine whether the coupon is valid for use. The expiration date tells the cashier if the coupon is still active or if it has passed, which would render it invalid. Additionally, the specific terms of the coupon detail conditions such as eligible products, limits on quantities, or minimum purchase requirements. By ensuring that both the expiration date and terms are valid, the cashier can confidently process the coupon in accordance with the store's policies, preventing potential disputes or errors at the register. This practice also helps maintain good customer service by ensuring that only legitimate discounts are applied.
