FROM：  Mr. Chambers

　　As President of this company， I was disappointed and humiliated by the behavior of some     [name of firm] employees who attended the meeting on     [day] The discourtesy shown to     [individual]     was unforgivable.  Some employees not only talked incessantly during our speaker's address but also exhibited the height of rudeness by leaving the auditorium before the completion of his speech.  To anyone who is guilty of these actions， I want you to know that such behavior will not be tolerated by this firm.

　　It distresses me to have to write a message such as this to you， and I certainly hope and trust that it will never again be necessary.
