How does a billiards hall attract customers?

Bring cigarettes with you at all times, communicate more with customers, and retain old customers. If you come here often, you will get a discount if you play for a long time. Nowadays, most people in the billiard room are 15-20 years old. Almost all of them are students in school, or those who have just left school and have not officially entered the society (to put it bluntly, they are all small gangsters). They don't have much money. As time goes by, they usually have a fixed customer base.
