Task: Question Answering
Input (English): Passage: I went shopping for shorts this afternoon at the shopping mall . I found the perfect pair of summer shorts in my size at my favorite store , and so I took them to the checkout aisle . When I arrived to check out , however , I realized that I did n't have any cash available . I pulled out the card , a blue Mastercard , and presented it to the checkout person . She took my card and inserted it by one end into a card-reading machine . This process ensured that my transaction was safe and secure , and that others could n't make unauthorized use of my card . She then handed me a piece of paper for my signature . I signed the paper and handed it back to her . She then handed me my receipt for the credit card purchase . Question: Whom did they ask to wait while they found their credit card? Option1: Security guard Option2: cashier
Output (English): cashier
