Most of our obstacles would melt away if, instead of cowering before them, we should make up our minds to walk boldly through them. Orison Swett Marden
A simple action, inflection, comment or gesture escalates into a massive business problem and no one can explain why. All business are beset with seemly innocuous events that have organizational survival implications at times.
The why is analogous to road rage. The unexplained reaction to another driver's careless driving maneuver. It is not the action itself that creates the issue, rather it is the fingers of instability that the action finds itself upon. If the self organizing critically is right, road rages erupts into a deadly confrontation. If the critically is not present the event is forgotten quickly and goes unnoticed into the dust pin of history.
Likewise a dropping of plate during an evening rush could occur and be forgotten or it could escalate into a event closes the business. It is not the event, rather it is the sum of the previous events that have occurred in the lives of all the participants that is the finger of instability.
