Accent or the way you dress maybe?
I'm told that they discriminate based on accents (eg. my mom apparently has a "countryside/villager" accent and when she goes to China people can tell) and the way that you dress as well (eg. dress like a fob/honger from the area not like a Canadian or whatever).
Also, the same happened to a friend of mine, even if he speaks Cantonese he gets crappy customer service.
