There is also a real possibility they did this many times before and it worked. I don’t really get it: if the thing would have broken on a Monday night and it would take a day to fix would that have been better?

The odds of someone screwing something up just before the weekend are way higher. Both because it’s obviously a rush job (it can’t wait until Monday), and because it’s the end of the week and folks are tired.

It’s just dumb.
