Question on Deck set up

While waiting for my seat at my local card room I noticed the floor going through a dozen box's of cards in search for 2 missing cards. Apparently they had found 2 extra cards at one of the tables a little earlier. They could not figure out where they came from as the other decks were complete. Now I wound up sitting at a table that was being opend so I got to see that all the cards were there. What my question is had I joined a game in progress would it have been out of line to ask to have the deck reset up? I have never done this and have no intentions of doing it in the future but i think this would be a case for it. I would appreciate your thougths
