Silly Sign

I like to pont out stuff that is, well, less than bright. This was a sign located in an exam room at my doctor's office. Now, it seems to me if I am reading this sign in the exam room, and I feel like I have H1N1 symptoms, than I am ALREADY in the building. A bit late don't you think? Perhaps I should have called the office and let them know that was in Exam Room 7?
