There was a sign on the door saying no more walk-ins for the day, but I asked anyway. Both the agent checking me in and the one who called me in for the interview responded with "we'll see," but they ended up calling him in as the next interview after mine. There was no one else waiting at the time.

I hope you have the same good luck!
