I did my shopping with my mother in law on 16 feb, 2011. At the counter, the cashier asked me : "are you a international student?" I felt weird but for politeness I said yes I am. Indeed i am a Chinese. But then she asked "do you speak English?" I felt very much insulted by this question. Can't a Chinese looking person speak English? Is that a polite question to ask? It's like asking a middle-aged looking person"so you are suffering middle age crisis?" what the hell was that!!! No matter how the woman whose name was Winner should watch her mouth. It is not her business to ask my occupation. And it is so bloody rude to doubt my language competence by my look.
