Bartender refers to the name of the waiter in an ancient inn or teahouse. We know that the clerk is only the employee of the store manager, and the store manager, as the real person in charge, is naturally the boss. Because such service personnel are second only to the store manager, they are often called shop assistants.

There is another saying about the origin of the title of shop assistant. It is said that there used to be a waiter named Wang Shi. He likes to write his name vertically, which makes him a "second pupil". Because he writes his name like this, people often call him Wang Erxiao. With the passage of time, the name Wang Erxiao was called Wang Xiaoer, and the name Wang Xiaoer became more and more fluent. Gradually, the service staff in an inn or teahouse is often called Xiao Er, that is, the shop assistant.

The appellation of bartender can gradually become popular in ancient times, which is related to the ancient cultural background. In ancient society, not everyone could have his own name. Many people living at the bottom of society don't have their own names. Similarly, as a bartender, his position is obviously not very high, and it is normal to have no name. In order to make it smooth, many people only have some random nicknames, and the probability of numbers appearing in these nicknames is very high, because numbers are convenient to call, and so is the bartender's name.

From the back of a simple name, we can also see the difference of ancient social status. No one will call the manager a shop assistant. After all, he is a man of more status. It can be seen that in ancient times, it was unrealistic for many ordinary people to want a very serious name. They only have a very casual name. For example, Zhu Yuanzhang, the founding emperor of the Ming Dynasty, was originally named Zhu Chongba. Later, his status was different and his name changed accordingly.
