What a miserable place. No one likes going to the DMV but they could at least try to make it as painless as possible? Instead they've implemented this ridiculous new "musical chairs" waiting system where first you stand in line, then move one chair over each time someone gets called to a window. And speaking of windows, expect only about 1/3 of them to be open.
The employees could also use a lesson in hospitality. No need to be so visibly miserable and frustrated with your job, and no need to snap at people or treat them like they're stupid when they have a question!
