回复：That rule applies to everyone. Not opnly Chinese!

My bad. I had a typo in the original post. Even though there was 3 person wanted to buy 3 IPAD that day, they only bought 1. Store manager refused to sell more than 1 to them based on the believe that they all buying for the same person. I think it's discrimination based on race for I don't see she refuse to sell more than 1 IPAD for 3 white people.
