One of my current boring tasks is preparing folders for work orders.  Apparently I prepared one incorrectly and received the following from an Eastern European Coworker:

Coworker: Terry.
Me: Yes?
Coworker: When you put sample drawings in folder, punch holes must be at top.
Me: Ok.  Does it matter?
Coworker: Does it matter?  Is vital!  I spend 40 minutes trying to figure out why drawing is upside down.  I created a whole AutoCAD file with upside down text and pouch spacing.  Then, I realized your problem and put new holes in the folder and had start over.  Now, paper is too light and when I go to file folder, I expect it heavier and slam wrist onto filing cabinet.  Is it important.

He told me.
