Yeah but does anybody believe that the engineers would deliberately break things so they could have to work in a stressful environment bringing things back up just to get some free beer?

If your incentives are aligned w/firefighting as opposed to fire prevention b/c management is not motivating and rewarding the extra work that goes into avoiding these scenarios in the first place, you're encouraging fire.

Indeed, the usual motivation to try and be called a hero for putting out the fire you started is much more valuable than free booze: a title promotion with a pay bump.
