The waiters of Fortune Restaurant were hired from other restaurants. They had been working in the restaurant business for a long time, and they more or less knew about how to survive at restaurants.
The head of the gang was called Changgui, and Changyi was the one that told the Imperial Master about the changing situation the day before. Both of them had been working in the restaurant business for a long time, with Changgui as a more experienced person. Therefore, Changgui was the head, whilst Changyi, the younger one, was also quite experienced.
Hearing what the Imperial Master said, Changgui subconsciously looked at Changyi.
Changyi found this idea good.
Normally, Changyi should have done something yesterday, but the Imperial Master did not think that it was worth any actions. However, the Imperial Master decided to do something today, so it wasn't too late. As long as the Imperial Master realized the problem, then that would be enough for Changyi.
