Watch Let's Go in Good Spirits (1941) Official Trailer

In the movies of those times, you can see young boys in the company scene often. Those boys were called kyuji (給仕), which means “waiter” literally. They are doing odd jobs in the company including serving tea, ushering visitors, buying tobacco, etc. Ordering lunch for the individual requests was also an important job. Those boys were hired often as soon as they graduated from elementary school.
