The public sector has no problem presenting a clear case for how the private sector works but it ends there.
For example, if you take a privately owned gym and allow public sector employee's to use it:
Private employed users take one towel (because the sign says- use one towel please), understanding the cost of maintaining the towels, etc. Public employee's use two, they are entiitled to two. They need two towels and therefore take two. They cannot make do with one towel.
