Ooou yes
There was a bizaviation company in Slovenia called Alpin aviation - they 'hired' 6 of us: 2 captains and 4 FO's. They (of course) promised us type rating on XL, women, parties on Flavio Briatores yacht, booze, drugs etc. Well, after two months of 'unforseen events' the 'CEO' simply didn't pick up his phone anymore.
I did some investigation work afterwords and found out, it was all an elaborate scheme - the state gives subsidies to newly founded companies for every new employee. The guy that tried to trick us (well, technically, we wouldn't loose anything) wanted us to sign the contract - we didn't want to do it, since we knew something smelled fishy. So we told him, that we will sign his contract when we see the airplane. He disappeared after that
After we would sign the contract (and he would get the subsidy), he would probably tell us, that something went wrong and he cannot pay us.
