Well yesterday was the day. Appointment was at 2:10 so we got there at 2:00, signed in, and took a seat. I was surprised when the supervisor came out a few minutes later, called off a bunch of names, and then called mine. (I'm guessing the others were appointments that didn't show up.) There were about five other people waiting when we got there that must have been walk-ins.
The wife and I had a trainee under direct supervision assisting us. I have to say both the supervisor and trainee were as nice as they could be. We had a scare for a moment because the only two govt issued IDs my wife had were her drivers license and her expired dependent ID card, and the supervisor was afraid the computer system would not accept the ID because of the length of time expired. Fortunately the "perversity of inanimate objects" gods were not with us yesterday.
They could definitely stand to have a few more terminals operating there, but that would require a larger room than they are currently in.
