I could just as easily specify another context where each of these actions are legitimate. (Perhaps free tickets are part of the theater worker's perks.)
If I said "I baked a cake for my mother," then you could say "BUT YOU STOLE THE FLOUR!" It doesn't prove anything.
My guess as to why it was not specified, is that the corruption is so obvious to anyone who has lived it, that it is easy to forget that others might not get the context. It's like someone trying to describe how fish live, but not remembering to remind people that water is wet.
That said, there were contextual clues. If you go back, I said, "You get what you need through corruption..." The next reply was agreeing and expanding on that. This strongly suggests that each step in the description involves corruption in some way.
That said, hopefully you're now clear that these blat networks involve pervasive corruption.
When a community that is used to blat networks moves to a different country, the blat network doesn't go away. Throughout US history, it has been common to see blat networks in immigrant communities turn into straight up organized crime. The most famous example being the rise of the Mafia. But it is hardly an isolated example.
