What if we look from another angle?
To install three screws for a weekend for 2000 each - it's okay, a half of a year is gained. At the same time, working on working days at the main job, earning for food - this is also where it went (although here is a joke about "you are still a lamp on my forehead hanging - I then and at night I will" remember).
But initially it was about the fact that he had earned himself in this way for an apartment in a few years (hence and half a year - three million (what) in six years). And I am a little more stunned - three million collected from installations of two thousand each - is 1500 installations of the pirate screw. Was he such a superhero? The Installer Captain? The Microsoft Man?
