[Sooner or later]

They can be perfectionist.

I was in Tyler as a new tire plant was being built. We had bought a bunch of state of the art equipment from a German company, Berstorf.

They sent one of their engineers, Helmut, over to oversee installation of the various pieces of equipment

On the day of the final install of the fabric wire calendar (produces sheets to later be cut into ply and steel belts) he was all over it. The base for this beast had already been set and laser aligned. The upper part of steel frame including the four 84" wide steel rolls was being lowered into place by a huge crane. The piece being lowered down probably weighed at least 10 tons. Probably more.

When the frame was about 4" above the base Helmut yelled STOP! He went to each base pad, took out a cloth, and wiped away any dust that had accumulated.

I thought to myself that any dust was going to be smashed to nothingness after the frame was completely lowered. He was just as picky during the other installs.

Oh, and thanks for the link.
