Friendly staff , however Waiting 40 mins so far after making an appointment for 12.45 and arriving 5 mins early ...Was apparently next in line?.... at least at the DMV you can see the numbers being called.
Update: once I got someone s attention told them when my appointment was supposed to be, and asked how much longer I d be waiting, they quickly organised for someone to see me.
