I stopped for dinner once at a Chinese restaurant in Mississippi run by people actually from China. I (white guy) used chopsticks and our server just stared at me wide-eyed for most of the meal. She said I was the first white person she had ever seen using them, and she'd been working there for years. That is Mississippi for you.
I didn't have the heart to tell her I'd learned to use them eating at Japanese restaurants.
Some fun chopstick facts: most chopsticks in the world (including China) are made in Georgia (the US state, not the country) because of the ready availability of cheap pine. One of the major reasons pine is so prevalent in Georgia (and in the US South in general) is slavery: cotton plantations in the pre-artificial fertilizer era tended to exhaust the soil after a few years, leaving pine trees as the only profitable crop that can be grown on much of the land.
