It's a shitty job, at least where I live. Basically, the quickier you do it, the more you earn, so people risk their (and other people's) lives on the streets every day, and since traffic regulations are as respected here as adultery laws are in the modern west, the streets are hell with all the motorcycles and bicycles coming from the wrong way and on the sidewalks.
Since covid, that profession really boomed, so it must at least be easy to get a job at that.
