Professional development scenario - Unruly spouse at a Unit Ball. Are you Sergeant Morales or Sergeant Audie Murphy material?

We are getting to that time of year, when many units will have the unit ball/formal before the end of the year. So how do you handle an unruly spouse? Here's the scenario:

This is a formal event. the receiving line is complete, ladies have been seated, colors have been posted, toast's completed, some early entertainment complete, dinner served to most of the tables, when.....

The spouse of one of the commanders in attendance approaches and addresses a General Officer early in the evening with anger over the seating arrangements and said she felt slighted as to where she and her husband were sitting. He thanked her for her concern and continued his conversation (he was the guest speaker, not the host).

About an hour later, they were introducing the guest speaker (the same General Officer) - she interrupts the introduction and purposely walks behind the podium and states loudly enough for everyone to hear "Thanks for your concern" and stomps off, standing at the door looking at the General with a scowl......you can hear a pin drop.........what do you do?
