As a clarification, when I called, I did not ask for anyone by name.  I asked about recent hires who were graduates of my schools.  In this way, nobody in specific was mentioned.  I then hung up and used their automated system to check for any employees named Specter; none were found.  So even if he had worked there, the receptionist would not know that I had checked.  In all of my actions, I protected the privacy of the people involved.  In fact, the only person whose identity was revealed was me: I gave my name.
