Hilary works at klothes kloset. she quickly the customers, and her cash drawer is always correct at the end of her shift. however, she never tries to "upsell" the customers (for example, by asking if they would like to purchase earrings to go with the shirt they chose or by suggesting a purse that matches the shoes they are buying). give hilary some constructive feedback on her performance.
