What does the closing effect mean?

Closing effect: in one sentence, people who didn't feel before have become feeling.

People's psychology is wonderful. There is a psychological phenomenon: as the closing time of bars approaches every night, the time pressure is getting tighter and tighter. If people who want to find a heterosexual partner in a bar don't pick one quickly, the bar will be closed. When someone may face loneliness again, such people will feel that they didn't like it very much, and it is becoming more and more attractive to wait for a better "the only thrill" in the back. In fact, when there is not much time left, people who haven't found a partner in the bar will feel that the alternative opposite sex is better than before. This phenomenon is not because people drink too much, but because people will have the same psychological phenomenon if they don't drink. However, this will only happen to people who haven't found a partner yet, and people who have found the "Mr. Right" will not have this psychological phenomenon. This is the so-called "closing effect".
