I saw it done to an extreme at a plant last week. they had everything labeled down to where the labeler was supposed to be! This place had one heack of a neat tool room, inventory bins, the whole place was sorted out like a show room. When I asked if the liked it the maintenance guys and operators said at first they hated it but quickly grew to like it. It made things just work better including work flow.
Messy environs lead to messy work.
As for napkins, thats my choice of note taking media!
