The reason I ask is I’ve seen food shows on the Cooking Channel in foreign countries where people are eating with chopsticks in their left hand, almost everyone in the restaurant. I’m ambidextrous but use my right hand for chopsticks. My father insisted that I learn to use them when I was 8, he was working with customers from Japan, Korea, Taiwan and Hawaii. Came in handy working with manufacturing consultants from Japan when going to dinner.
