I had this thought yesterday when a friend called and needed me to cover for him at a misdemeanor arraignment. I didn't even really have to go to an arraignment. I just needed to enter a written plea of not guilty and waiver the person's appearance in court.
Every jurisdiction has its own quirks. Cincinnati is no different. First I went to Room 117 to pick up the form. Then I went to room 113 to give the form to the clerk who had the file. Then the clerk brought that file to 117 and met me back where I started.
If you didn't already know to do that you might have found yourself confused and running in circles. Local lawyers know these things. They know how to deal with them. So in addition to the big picture, sometimes we just help keep the stress level down with the little stuff.
