According to my senior researcher who works at a cabaret, girls working there guess all the university students are wise and attractive. It is because most of the girls have low academic careers and then don't know systems of universities in detail.
So, the senior researcher could attract such girls only by saying that he is a graduate student, which is higher status than a university student.
So, we may make sweethearts in cabarets. But, the problem is that they are totally so foolish that they can cause some troubles.
