Task: Question Answering
Input (English): Passage: Last week my mother and I decided we wanted to go to a fast food restaurant . We chose Burger King because we enjoy their food . We drove up , parked our car and got out and went inside the restaurant .  After a short while , I stepped up to the counter and placed my order with the customer service guy . He seemed nice and friendly , which helped . I order a burger and large fries and a coke for myself and a burger and fries and a salad for mom .  I waited about five minutes and my order was placed on a tray for me to take to where my mom was sitting . We began eating our food while making small talk . I also got extra ketchup packets for us both .  After an hour or so , we were finished and we took the tray and dumped our remains in the trash .  We 'd had a nice lunch together and were ready to go . Question: When did he ring up the order? Option1: Once they arrived Option2: When they placed the order.
