Only a FBI NICS Legal Documents Examiner is authorized to delay or deny a transfer.
A number of states run their own systems instead of using the NICS, FBI folks aren't involved in all states. I don't know where Tom Servo is from, but this might explain the difference in procedure.
Which brings us back to what johnbt inquired about. What state is the OP in? Reasons for a minor delay in a state run system might differ from reasons with the NICS.
