i think it is best to eat whatever food with the cultured cutlery. this is to enable you to know the cultures about the origins of the food. let's picture this, if one is to use his/her preferred cutlery when eating other culture's food, it will be somting like=
eating makis and sushi with fork and knife??
eating prata with chopsticks?
eating medium rare steaks with bare hands (some food don't need to use cutlery)
i don't know why, but for me, i actually think that people are hopeless when eating home cooked food using fork spoon. if u are living in sg for so long and still cannot grasp the art of eating different culture's food, then u are still living in under a rock.
