I like irony, and if you pay attention you can see a lot of it. The "I don't do that safer thing because it is slows production down" argument is common in every single industry on the planet. My favorite is when they use coat hanger wire to bypass the safety devices on equipment, because it's faster.
In every case when I've asked "how much faster?" the answers are always related to a few seconds or a minute saved each time you do it. Then multiplied by how many times the action in question is performed. But, never do they look at the time savings over the course of the work shift... because there is LOTS of time lost to stupid shit over that time. Somehow, though, those seconds or minutes saved are important... more important than the twenty minutes they wasted smoking cigarettes outside the back door when the boss wasn't looking... more important than the fifteen minutes they spent smoking weed in the bathroom four times in one shift... more important than the slowed down production caused by them shooting the shit about football or blaming China for making stuff for American companies... more important than the three days of lost production because some dumbass used a coat hanger to bypass the safety devices on equipment just before an OSHA inspection.
Nobody ever says, "I one-hand my chainsaw because I think it makes me look badass!" or "I one-hand my chainsaw because I'm an impatient idiot and I'm too lazy to get better positioning!" or any other, believable reason. No, it's always "It's so much faster!" when anyone who's done it knows perfectly well that it's only slightly faster on a good day.
I'm not like that, at all. I one-hand my chainsaw because my pecker is so huge, that if I don't keep one hand on it, it will flop out and the tree will snap off at the ground.
