It's not that bad here. All the people I have encountered here have been really friendly even with the customers that are rude they seem to stay calm. Last couple times we have come in right before they stop handing out tickets (which is 4:30 btw) both times they have quickly fit us in.
The only downfall is the place is small and not a lot of seating. Not really sure if the AC is operable, it always seems so stuffy in here .
It is the DMV guys so expect to wait. Pack your patience, breathe and smile :)
