In many places, but especially in Thailand, when you sit down to eat, they will give you a spoon and a fork. You cannot, under any circumstances, put that fork in your month. I have never figured out why it is rude(not rude as in offensive, but if you eat with a fork you will get a lot of stairs and some head shaking), but everyone knows it is and no one ever puts the fork in their mouth. Instead they use the fork to shovel food onto their spoon. The spoon can go in your mouth.
You might be thinking, ‘Thailand has a lot of noodles and I need a fork to eat them. Nope. If you are eating noodles they will give you chopsticks. If you can’t use chopsticks they will give you a spoon. You will never have to eat with a fork, so do your best, and never put it in your mouth.
What about pieces of meat or fruit? Well yes they will sometimes give you a fork, or so I’m told. I have never been given a fork for these. Instead they give me over sized toothpicks to poke the food and carry it to my mouth.
