That DMV office has been like that for years. I don't believe for one second they have any real help coming, of course they are going to say that though when pressed about it. Also there is a sign inside that says the workers are not state employees but contractors from an outside company.
When I need to go to the DMV I just go to the Hampstead or Burgaw branches. Last time I went to Hampstead to have the names on my title changed I was in and out within 5 minutes. I went to Burgaw in January for a renewal and wasn't there for more than 10 minutes.
