Why were waiters in ancient hotels called "shop assistants"?

We often see that the waiters in ancient dramas are all called Xiao Er. Xiao er's name comes from the ancient people's address to young people, so in the end, people all shouted, Shop Xiao er.

The "bartender" refers to the person who is responsible for services such as post stations, teahouses, hotels and so on. So, how did the name "shop assistant" come from? In ancient times, there was a waiter named Wang Shi in a restaurant. According to the writing habits of the ancients, waiters often wrote their names as "Wang Erxiao", because he wrote the upper and lower structures of the word "Shi" too far apart, and he vividly wrote "Er" and "Xiao". People called Wang Shi "Wang Erxiao" half jokingly. Over time, people find it easier to be called "Xiao Er". So Xiao Er called out slowly, and later people called the waiter Xiao Er or Xiao Er in the restaurant.

The story is reasonable at first, but there are many unreasonable places to consider. The ancients went to school just to get a learned name. When they are officials, they have official names. Ordinary people like Xiao er are generally not famous. But Xiao Er in this story not only has a famous name, but also a rare name "Stone". In fact, few people use this word as a name, which is one of them. Secondly, the king showed "Wang Xiaoer" without any "great" deeds. It's hard for people to remember him, and it's hard to make him an industry spokesperson.

In ancient times, young people in society were generally called "Xiao Er" or "Little Gore". In ancient times, young people worked as waiters in hotels. In the long run, people will call them Xiao er. It makes sense to call him a shop assistant. The shopkeeper is naturally the boss, and the bookkeeper is called Mr. Compared with them, the clerk is of course both "small" and "second".
