@yanche......unfortunately you give them waaaaay to much credit for having any level of common sense and ability to apply their limited technical knowledge.
Like me, I know you have worked on gov't contracts....think about some of the requirements you have surely had to work around and between to get your job done......you should know better than that!
A good one I heard this past winter from the maintenance manager at a local plant that makes medical needles is that he has to go through an FDA authorized verification checklist and get three management signatures for any landscaping work on the property. If they don't have them on file they get a 'violation' from the FDA and lose their approval for the needles. So any snow plowing, grass cutting, flower bed mulching, tree trimming, leaf raking, etc, is covered.
