You would think that closing down a FSDO would mean the FSDO provides no service, but I found the opposite today.
Weeks ago I sent an email to get WINGS recognition for a seminar that I'm organizing. Nobody replied until today, when the government is shut down. The head of a FSDO phoned me at home to ask me if I still wanted to arrange for WINGS status for the seminar.
He told me that he was the only one working at the office during the shut down. I suppose he was deemed to be "excepted" or "essential."
What that seemed to mean in practice is that it was nice and quiet so that he could catch up on work, even if the work isn't very "essential."
