Philbert the Floss-bit

There is a piece of dental floss in the middle of the hallway of my office. It's been there for a little over a week. It's in such a position that every employee walks over it several times a day. It got there because someone flossed their teeth in their office (nice) and then threw it away, and the guy who empties the trash did a poor job of it and it fell out. I haven't touched it because it's become an interesting social experiment for me. How filthy will this place get before the bosses will do something about it? My guess is "Quite".
