An Experiment at a city government Department

A city government department (such as Municipal Corporation) keeps a dropbox called "Complaint Box" at their office and on their website to better attend public's grievances. But there is no "Thank You" box at these locations.
Placing a "Thank You" box will be an interesting experiment. It will tell something about the public and the government body.

Public could be characterised in following two ways:
Always complaining, never owning issues of others, and wanting a channel to divert the anguish of their personal lives. The unfamiliar and impersonal city government body is perfect choice for such a scapegoat.
Or, Public that can appreciate the great work done to the service of the city by that government body. They just don't know how to thank them.

Similarly, the government body could be portrayed in these two ways:
Actually never caring about the city and complaint box is just a sham.
Or, It does its work honestly but is frustrated that public is never happy. Each time public would raise the bar of performance to new level. They don't get a thank you note from the public, may be because the public doesn't know how to.

This second dropbox will tell what public is and what the government body is.
