Every single established procedure we have at work which are there to prevent people from shooting themselves in the foot, which they instantly forget if they haven't encountered whatever that situation is in the last, oh, three days or so. And then proceed directly to shooting themselves in the foot by making up their "own way" to handle whatever it was because "they didn't know what to do," which then turns out to be wrong 100% of the time. Which is why we have those procedures in the first place.
