An established patient, Mrs$.$ Barker, is in the waiting room and the physician is running behind schedule. You had called her prior to her leaving her house and advised her that the physician had an emergency and had not returned to the office. You asked her if she wanted to reschedule; she choose to come at her scheduled time. After she waited for about $10$ minutes she started complaining, and after another $10$ minutes, you approached her and asked if she would like to run an errand and then return, remain and wait, or reschedule. She insisted on staying but has become very loud as she complains about the office always running behind schedule. How would you handle this situation?
