When eating western food, the waiter brings a glass of lemonade. Why is it "disgusting" to drink?

In daily life, everyone's diet is special and particular. As usual, each of us wants to go to a better western restaurant with our family and friends. Taste its delicacy, because the location of the western restaurant is not only very good, but also has very delicious food. You will find it exquisite when you look at it again, but many people don't know that if you go to eat western food, you may be rejected if you don't pay attention to etiquette. When eating western food, the waiter washes his hands with a glass of lemonade.

When people eat in China, spoons and chopsticks are essential, but they are totally different from western food. They usually use two types of knives and forks because they pay special attention to eating at that time. They also make people feel very cautious, and generally eat less when eating, because we all see that there is very little food in a plate of western food. Nowadays, many young people, including them and their friends, especially like to come to western restaurants to taste delicious food, but this is precisely because they don't understand and may make jokes.

When we eat in a western restaurant, usually the waiter will bring you a glass of lemonade when he sees you. It seems that many people will quench their thirst when they see lemonade. In fact, this lemonade is not suitable for drinking. If you drink lemonade, it can be said that you will be rejected, because lemonade can make you wash your hands, but many people don't even know the meaning.

Because there are many steps in eating western food, such as the different usage of knives and forks, and washing hands before meals is the habit of using lemonade directly in some places. When we see it, it usually means that lemonade is not suitable for drinking, so we must pay more attention when eating. But if you want to know whether lemonade can be drunk or whether you can wash your hands, it's simple. If you see a round cup, you can drink it without any problem, but if you see a square cup, please wash your hands before eating.
