Dealing with ambiguous complaints

Wu Fei, from China, works as a co-manager of a Yakiniku restaurant in Tokyo. After graduating university, she moved to Japan in 2010 and began studying Japanese. She began working at this Yakiniku restaurant last year. Besides waitressing, she's responsible for store operations and training new staff members. Her Japanese is great, but sometimes she finds it hard to deal with ambiguous complaints from customers. She tackles a roleplay challenge to help her improve her customer service skills.
