My ship threw tools and parts overboard before pulling into a long shipyard overhaul because they knew they would get more.
I knew shipyard workers who got told to come to work and do nothing so they could mark billable hours (worker gets paid, contract is making money on the workers hourly, so who loses? Not counting the dipshit American taxpayer, of course)
New equipment installed with copy and pasted filters, except new equipment has 100x flowrate so filters last weeks instead of years.
Whole system overhauls descoped from the shipyard maintenance plan so the ship could be delivered "early" and bonuses paid.
Cheney and Halliburton?
Stories too numerous to mention. Only someone who's never seen this up close could think we're doing the cost efficient, safe thing.
