I once worked at a Fortune 50 company where keeping your budget low was something that upper management (at a certain level) was not happy with. We once built a hadoop cluster because we needed to "burn" some money (~$150k) left in our budget. In this company coming in under budget meant you didn't do a good job of forecasting your needs so you were punished with budget cuts the following year. That led to so much waste. Coming from a startup where saving a few hundred dollars/months was something to celebrate it was mind-boggling to see all of the waste.
