Yeah always be careful with that. I worked with a White guy that grew up in a Chinese family (adopted) . We were in a restaurant in the Asian part of Seattle. Well according to him they were talking bad about us the whole time. White this Black that for like the whole hour we were there. Then as we are getting the check he spoke in perfect Mandarin no accent or anything. You could have heard a pindrop and the look on their faces. It was epic.
