Thank you, Gerd, for the link to the video which I have now watched.
Interesting, the differences in services offered to perhaps "upper middle class" households in 1928 compared to today.
Pat and I live in what I would consider an "upper middle class" home in a suburb of Atlanta, Georgia USA. We pay not only the regular city and county taxes for various types of "general" waste disposal but also a private company to take away our household waste on a weekly basis.
We have one large barrel for "normal" waste and one for "recyclable" waste. Both mounted on wheels.
In watching your video, it seems there is a dedicated person to fetch and then return the barrel inside the gate to the household. He does nothing else.
In our case, the house is more or less 1,000 feet from the roadway (300 meters), and it is all downhill and uphill as the house is on a hill. It is our responsibility to take both containers down to the street and once they are unloaded, bring them back up the hill.
The chap on our waste truck (there is a driver and a "dumper") rides on a pedestal at the rear of the truck and he jumps off at each home, grabs the two containers and fits them into a dump system similar to the subject of the quiz except that it is a single central entry dumping hole and the system mechanically picks up the container and dumps it. One at a time.
After that is done, said "dumper" does just that with our containers. He just throws them back towards the curbing, often tipping them over and the truck moves on.
Quite a difference from the 1920s I think.
