A memory of a part time job

I live in Tottori prefecture which has the smallest population in Japan. Usually trains are not so crowded, even in the morning. However, it was crowded more than usual yesterday and I remembered a memory of a part time job many years ago.. Until this January, I lived in Tokyo for over 20 years, which is over 20 times bigger than Tottori in population. When I was an undergraduate student of a university in central Tokyo, as the general case in Japan, I worked a part time job. (or I worked part time) I worked at a station near the university before the first lecture. What I did was to open doors of the train cars and push commuters into the cars. Do you understand?
