None of those examples you gave sound like corruption to me, with the possible exception of tickets. It seems to me that the problem is when people who are in a position of power and responsibility abuse their power for personal ends. Plumbing or tutoring or cheese are privately held goods and surely the possessors of those goods can dispose of them how they want?
Or perhaps in all of these examples the plumber/grocer/engineer is entrusted with responsibility from the government to ration a scarce resource?
Yea, I guess I don't get it either. I know someone who can eat at a local restaurant for free whenever he wants because he knows the owner. In return, he helps the owner maintain his car and does little odd handyman jobs around the owner's house for him. Is this blat? Is it corruption? Or is it just friends doing each other favors?
Well in the Soviet case, plumbing and cheese are most certainly not privately held resources. Doing such work as a plumber means you're essentially acting as self-employed or a business, which is illegal. The cheese is probably produced on a collective farm and sold at a state-owned store.
But surely the cheese case would not be okay even in a Western capitalist context where the store is privately owned. Just replace it with a more scarce product. A store employee isn't allowed to tell customers the store is out of iPhones while keeping a dozen stashed for preferred buyers.
Corruption like almost all things fall on a spectrum.
Those are examples of soft corruption

Is that not the definition of corruption?
They are all corruption, or corruption adjacent.
The plumber is working for a company. He's supposed to be working on an official job. But he's doing the work slowly because he's actually working on your plumbing problem.
You are working for the grocery store. You are stealing cheese from the store system that is supposed to allocate it, and making it available it to the plumber as payment for your plumber being corrupt on your behalf.
Again, the wife "who can help you get tickets" is stealing access to them. That's corruption.
The engineer who is tutoring, is paying for that act of corruption. This may or may not happen when the engineer is officially supposed to being doing something else as part of their job. If so, that's possible because people learn to look the other way for you, so that you'll look the other way for them.
And in a society where everything works this way, what do you think happens to overall economic productivity? Exactly! Which creates scarcity. Scarcity that makes the ability to get things through the blat network even more valuable!
