Dr. Holmes himself became angry when one employee, Roy Trenneman, scared the woman who was getting her stress levels measured, just to see the machine go crazy measuring her high stress level. Roy angered Dr. Holmes so much that he later shouted at him and his friend Maurice Moss as well as at a crying woman, despite just talking about the importance of controlling anger. When Dr. Holmes later met Roy at a lift, he lunged at him because of the incident caused at the stress class. Roy managed to escape the furious doctor and even managed to steal his stress machine.
