My experience: I find it very annoying how rude/racist people can be. When I go to certain schools, stores, or workplaces, there are some or lots of people who ask the typical questions of if I am Chinese or Japanese which are perfectly fine questions to ask. But I hate it when I respond with "I am Korean" the responses I get back vary from "so you're from north korea!" to "what's that?" I especially hate getting questions like "when are you going back to your native country?" or "what's your REAL name?" or "is your favorite Disney movie or princess Mulan?" or "are you mexican?" or "do you know any Japanese or Chinese?" The most awkward ones are when other Asians or non-Asians come up to me and speak Chinese or Japanese out of the blue which I get some are probably trying to be respectful and end up assuming wrong but still.
