Most Kings/Emperors in real life or fantasy have/had a throne room and part of the reason for the existence of said room is to meet with other dignitaries, officials, royals etc., but also to grant audience (from time to time) to commoners(*), as was customary for Byzantine emperors, French Kings and so on.
So my question is: Did Emperor Palpatine ever grant audience to a commoner?
I don't remember this ever happening in the movies so far, so EU answers are acceptable. Also, Luke in RotJ was admitted in the throne room after the Emperor's "request", so it doesn't count. Furthermore, Vader was the Emperor's head-honcho, so he also doesn't count.
(*) Commoner=Not royalty, not a member of the imperial navy or any other high ranking official.
