I think it is very important to measure the quality of a country's citizens, whether it is a subway station or something else. At present, most people can still abide by social order, which is also the embodiment of social progress. As for jumping in line at the subway station, in the first case, TA may be really anxious and occasionally jump in line. On the other hand, I believe that TA will cut in line at any occasion to take advantage of it, lest it "suffer". Because such a person who loves to take advantage of petty advantages will certainly be humiliated by people around him in life and despise his quality. Therefore, I think it is really pitiful to treat such people.
