Playing Dumb Asian

Some Asians really don't know how to speak English. Some Asians may also be dumb. However, some Asians only pretend to be dumb and bad at English to get free stuff. This primarily happens with girls. I have never heard a male customer doing this. Some will make cute noises to indicate their apparent bafflement. But basically they act like they don't understand you when you tell them something they don't want to hear, even though they probably know full well that the order total is that high, that the coupon has already expired, that the policy doesn't include that particular promotion or free shipping.
