How to communicate with customers in Macao's barrier field?

The result was tragic. My friend is a super invisible rich second generation, but he never treats guests at ordinary times and likes to go to Internet cafes to play games. Until one day, we traveled to Macao together, and we went in to have a look and have some fun. I believe that most people think so, and they never thought that they would fall into it. But things are not as simple as you think. In fact, people who run casinos can be said to be at least 10 times smarter than us mortals. Psychology has studied human weakness. Unless you know how to stop. Secondly, there is no cheating. Only the countryside will cheat. People there will crush you with huge sums of money. Your money is limited, and his money is unlimited. You will always lose in a protracted war unless you know how to stop. But too few people can stop. You get 10W as soon as a friend enters. We just learn and follow him. First I won 5W5, now I have confidence. He went somewhere else. After many times, he gave up and bought a casual one. He won 1W and now he has 165000. We all advised him to stop, and he agreed. Let's go downstairs and change chips. Passing 2 1, I couldn't help but go up and play two games. He said that the worst thing was a draw. I won't move the capital, so we'll go together. Then suddenly he only lost 10W. It's time to go now. He didn't. He said, Alas, I have lost this 10W before anyway. Goodbye. How dare we let him go? I'll accompany him downstairs and the others go upstairs. At this time, it is high there, and all the voices are winning, giving you an illusion. Twenty minutes later, I watched him lose 70W, and the people upstairs came down and said they couldn't sleep. It seems that everyone is winning money, and then he wants to change, so we have to pull him out. Later, when I asked him, I realized that he lost 470W overnight. He recalled that the more he played, the more he wanted to get his money back. We were all stunned. Later, I heard from him that there were many doorways. For example, it's easy for you to change chips, but it's a long way to change chips for money, and there are new projects on the way to attract you. People shouted as if they were all winning money. Then there will be vents to fill it with oxygen, saying that people should breathe more. In fact, pure oxygen can make people feel excited and can't sleep. This will also come down to play. But when he came out that day, he was more sober He said that if he was still in the casino, we wouldn't detain him. He is going to use 1000W, and he will stop if he loses. But everyone knows that it is impossible, and he will not stop until he loses everything.
