The answer to the question?
Yes, when your in a chinese or korean restaurant but a big NO - NO when eating Thai. Except, when tucking into a luscious Laksa or other hearty noodle dish. If you're eating rice, please use the forks and spoons provided.
Why, you may ask?
Well, in Thailand, the use of chopsticks is frowned upon and considered bad ettiquette unless eating noodle dishes. So, next time you're in downtown Bangkok, don't ask for chopsticks unless it is offered. Otherwise you may get surprising looks from the locals around you.
