I heard a very unpleasant story from Alyssa that a worker of that restaurant asked her once if Malaysian Chinese hate Chinese from China. I was astonished when I heard that. May be there are some black sheep out there that do hate you, but what the heck does it how to do with her? A customer is a customer, you must never ask something as foolish as that and you do not have the rights to ask that as well.
Moreover, a Chinese waiter with a "super black face" who served my table poked me at my right shoulder or appeared behind me without any notice like a ghost each time he served a dish. I felt really unpleasant when he poked me each time. Alyssa also noticed the "black face" of the waiter.
When we walked out from the restaurant, he was standing at the exit and said thank you. I didn't even bother about what he spit out from his bullshit mouth.
To that waiter, two words for you: "Fuck you!"
