Left fork and right knife, you know this, and generally speaking, soup is served in front of the staple food, so the spoon must be outside the fork.
Usually, I am used to holding a spoon with that hand. What needs attention is the gesture of scooping soup, which must be scooped from the inside out. Be careful that the spoon can't touch the bottom of the plate and make a rubbing sound, which is very impolite. eat and drink well
Answer to the supplementary question: I am sorry that the landlord made a joke in front of me, because I have never been to a western restaurant to eat rice dishes. Generally, the staple food is meat and fish, so I specially asked someone who understands it to help you ask-when eating rice and other dishes, you can scoop up a fork from the front with your left hand, because the concave part of the fork is designed for this usage. At this time, you can also use a knife to assist the dining action. When scooping the dishes on the plate, use a knife to prevent the dishes from scattering outside the plate, so as to scoop the dishes on the plate clean. You didn't mention using a spoon. Sorry, I may not be able to help you.
