Fit to Be Tied

I wear a tie to work 4-5 days a week (but not today, with a mock turtleneck under a dress shirt, which I can do on certain days), and of course have developed favorite ties.
I wore one of them to work yesterday, an olive/khaki tie with gold diamonds and some brown trim, as part of a suit coat/dress pants outfit. When I got to work, I found that there were two stains on my tie I didn't see at home.
Fortunately, the stains, near the bottom of my tie, were basically at the perfect height for where the electronic name tag I wear (access to secure areas, etc.) hangs. So I was able to hide it, with the suit coat making the stains even less apparent, but now I really have to go to the dry cleaner.
