What is the behavior of socially recognized city cleaners and property sanitation workers to extort waste materials from businesses in their jurisdiction under the guise of cleaning?

First of all, I think the cleaning of the property sanitation worker is his duty behavior. In the management area, it is not necessary to use the word blackmail to take away unwanted waste materials through business negotiations. I am also a vulnerable group, and being able to help others is also a manifestation of a happy life, or a way to live in harmony.
