1. Be confident and speak loudly. When someone cuts in line, I want to know what he did wrong. He doesn't know the basic qualities. I am helping him to correct his mistakes, but I am educating him. I will affirm my position and bravely tell him that it is wrong to jump the queue and I can't lack confidence. I will remind him loudly but quietly. The purpose of speaking loudly is to make everyone notice him and make him feel ashamed. It should be noted that speaking loudly often leads to emotional intensification, so the voice should be as calm as possible so as not to make the other party feel scolded.
2. Be calm and have a good attitude. I want to keep a tolerant attitude and not be angry, which will only make the other party angry and often lead to more serious consequences. Be sure to keep a peaceful mind. In any case, it is always the people who jump the queue who make mistakes. Just correct him. Tough attitude. People who often jump the queue are thick-skinned. People who jump the queue like this are indifferent, and many people will choose to give in because of this, but blindly giving in will often lead to more rampant jumping the queue. So, be tough. If the person who cuts in line refuses, we will stand directly in front of him.
