This is called corruption. The first part,where you were asked to stay longer than needed is just a form of overbooking,where one declares the scale much greater than it actually is.I've seen this being done on a smaller scale,where instead of 5 people, company brings in 15 and then the extra 10 just wandering around nit doing much, however the end client is being billed as it was a job for 15 men.The other example was where a 1 truck of bricks turned out to be 15 trucks on paper...Again,the end client is charged. The part with drones is most likely where the locals with the right connections in the border services create some random company,then public tender is made in a way thst it just fits this new conpany. Once the contract is won, they'd buy drones from the major players anyway,just with a nice margin on top of it.
