Once was installing drains on the roof of a large building. Pulled out the blueprint and it said some of the drains should be installed in the empty part next to the building. You know, the part where there is no building in need of drains. Heck'n dinguses. Did you know the union I used to work for used to have a drafting team that contractors would have to hire to design the layout of what we built and installed? Now the contractor gets to do it and our union members just gotta do their best with what they give them.
