In the county where I live, there are half a dozen offices. I am very lucky that the one most convenient to me is also the quickest.
Even more lucky, in Georgia, after the first time, most license renewals can be done through the mail.
We just got my daughter's learner's permit, and it was quite painless. It took two visits to an office 15 minutes from my house, the first time it took an hour and that should have been enough, but we forgot something and had to go back a second time for half an hour.
I was careful to time and choose my visits (eg on a rainy Tuesday afternoon) to avoid the crowds.
But I shouldn't gloat - I hate long lines, too.
