The other day I as well as my parents was eating in a restaurant while we noticed a foreigner coming in. He seats himself at a table by the window. Soon a waitress came and wanted to take order. However, the foreigner couldn't got his needs across. Seen this, I went up immediate to offer some help. We communicated with simple English for a moment but I later knew why the waitress couldn't understand him. The foreigner actually wanted a roast Beijing duck, but he had a wrong Chinese pronounce. Hearing my explanation, the waitress couldn't help to laughing. The foreigner himself also laughed.
