re: Do you own chopsticks that you bring to Japanese/Vietnamese/Thai restaurants?

I sat next to a couple at the sushi bar one time who had their own. I struck up a convo with them as they were also wearing leather vests and well they brought their own chopsticks that were in little cases. Their thing was to ride their motorcycle around and go to different sushi restaurants... Probably had one of those 3 wheel bikes with a little trailer on it too. To each their own I guess.
