Symptoms:
Bill and Pat were returning from their monthly poker game and while riding back in the car they both agreed they had witnessed a situation that they could apply as a "lesson learned" to their business careers. Everything had started out very similar to an everyday business meeting or sales call with socializing and normal banter between participants, but about half way through the event something had gone bad.
A simple mistake had been made that resulted in some subtle and not so subtle accusations leading to lines being drawn about who was right and who was wrong. All of a sudden everyone was very uncomfortable with the tone in the room.
The "accused" had snapped back with a defense based on fairness and leniency (not results) that almost guaranteed a confrontation between the two sides. The emotions ranged from excuse making to embarrassment to anger and then to withdrawal and alienation as the aggressors piled on the wrong-doers. When the game broke up early, everyone knew it had been caused by too much bad behavior.
