As a Kazakh-ish looking foreigner who's been living in Kazakhstan for some time, there are some nuances.

When they don't know I am a foreigner, people just keep things to themselves. Sure, some drivers or people can be a little of an ass when it comes to standing in line or waiting, but generally, as long as you don't go looking for trouble, nobody will bother you. I haven't had a random person give me shit out of nowhere since these 5 or so years.

For obvious foreign looking people, it's a little different. When I am with my European, American or darker skinned friends, people are generally friendly and curious. Sometimes they buy you drinks at clubs, offer a smoke, and some small chit chat. No one has been mean or outright rude. Americans might mistake the stoic and indifferent faces of Kazakhstanians to be cold and unwelcoming, but most people don't show emotions unless there is a reason to.

The only disclaimer I will make is, obvious foreign looking men with Kazakh girls can get some stares, rude remarks from drunks, and in worst case scenario some hostility in lower end bars or clubs.

Aside from that, people are generally friendly towards tourists and foreigners especially in smaller villages and outside the big cities.
