If a person, when ordering food, does not consider other people's tastes at all, only orders some dishes he likes and wolfs them down after serving, this is probably his most real life state at ordinary times. One of my former colleagues, because he didn't like to eat certain foods, always picked out the food in the bowl one by one and threw it on the table at will. At the end of a meal, there were dishes picked out everywhere in front of him, which made people at the same table look uncomfortable. This behavior is really convenient for yourself, but it has caused great inconvenience to others.
A person's attitude towards service personnel also shows his personal accomplishment. In our life, many people always hold the view that the customer is God, bossing the waiters around, or being choosy and not cherishing the fruits of others' labor. These people's personalities can be seen. A truly educated person must be a gentleman who knows how to cherish the fruits of others' labor and treat others equally.
When eating, always drink, and wine is character. We often see drunken revelry, beating people, forcing others to drink knowing that they can't drink, and even disturbing the dining environment of others. A truly literate person will never do these things that harm others and themselves. They know where everything is and respect themselves on the premise of respecting others.
Since it's a mixed meal, it's usually AA, and everyone has to pay their share. Some people don't think so. They always want to take advantage of others and don't want to spend more or not. Eating such a small thing will expose a person's nature, so there is a saying: if you want to know a person, go out for a meal! This sentence is very practical.
