Nice.
Usually not the case.
Usually done by someone who found themselves in just a little financial pinch and decided to borrow some of the cash to tide themselves over. They fully intend to pay it back and often even do so. The first few times. But once you start you don't stop. And you pay back a little bit less and not quite as quickly. You work hard and you are not paid enough and it is just a little bit....
Soon you have a mess that even if you wanted to clean up you can't and now you are afraid of being exposed. And that is just with the weak ones. If they have a secret heart of darkness thing going that they have suppressed because of a fear of punishment things get really bad.
If you have yearly audits they will not take the first unauthorized loan because they know they will have to explain it very soon.
