What’s the point of giving a bottle of water to the electrician?

Seeing the hard work of the electrician, I brought him a bottle of water. This joke describes a master electrician who was sweating profusely in the hot summer and repairing wires for customers. It was very hard. In order to express his gratitude, someone handed him a bottle of water and said, "Master, have a drink of water." After the electrician took a sip of water, he said with emotion: "You city people are still in trouble. I have repaired wires for so many years, and only After entering the city, I learned that there is a kind of water called pulse. "This joke mainly expresses the electrician's surprise at the routines in the city and his discomfort with modern life in a humorous way. At the same time, it also emphasizes the hard work of the electrician and people's gratitude to him.
