Reminds me of growing up with my dad. You bend a nail, you don't reach for another one, you straighten it and then use it. He designed the house that I grew up in and when I say designed, I mean he had a blueprint for everything. He spec'd out exactly what length boards had to be used where to get the most out of each cut of wood. He even calculated exactly how many of each size nail that would be purchased and where each was to be used. He contracted a guy to be the GC and was very clear that the materials on the drawings would be the ONLY ones provided and that if they made a wrong cut or had excessive waste, it was coming out of the GC's pocket, not my dad's. Sure enough, everything was built to spec as though they were building one big-ass Lego set. Only problem came when the flooring supplier sent the wrong materials to the build site and the flooring contractor installed hard wood floors upstairs (didn't bother to look at the plans, just "went from his gut", thinking that my dad wanted hardwood floors in the upstairs bedrooms and hallway. After they were sanded and sealed, my dad asks them, "Didn't you read the plans?" Nope. Flooring supplier had to deliver carpeting and the contractor had to install carpeting over finished hardwood floors. I wasn't aware of it growing up, but later in life when I bought my parents' house and started to remodel did I pull up the carpeting and find beautiful finished hardwood floors.
Yes, my dad was THAT guy that waited until they had finished the job before pointing out their mistake.
