Sit on the podium first (there is no podium, the door is the innermost), and the leaders sit at the back in order of size. The leader must be the last to arrive then. Colleagues who come first will chat and eat small plates according to the arrangement of both men and women, and they can drink and have fun in the back row. We must ask the man to get a witness and the woman to get a witness. This is a vibrant and harmonious society.
