When the steak is served, all you have to do is fork the meat from the left, and then cut the meat with a knife along the right side of the fork. If the cut meat can't be eaten in one bite, you can directly cut it into smaller pieces with a knife, cut a piece of meat just the size of a bite, and then send it directly to your mouth with a fork.
When you cut the steak with a knife, your forefinger should press on the back of the knife and fork. It should be noted that you should use force when extending the knife, not when drawing it. Eat every piece of meat you cut-don't cut it into small pieces at once.
If there are big bones in the steak, you can ask the waiter to help you remove them, especially for women who don't have this skill. It is impolite to let the knife and fork come into close contact with the plate and make a loud noise.
The vegetables beside the steak are not only for decoration but also for balanced nutrition. Unless you really don't like it, you'd better eat it all.
6. When the steak is served, the speed of enjoying the steak can determine whether the steak is delicious or not. Because there is both butter and blood in the steak, the lower the temperature, the lower the freshness, so the steak must be enjoyed as soon as possible.
