Fun And Unpredictable
Despite the fact that his coworkers had a favorable impression of him, it was impossible to predict how entertaining and unpredictable Scherb would be. While he was on the job, he wore a mask that concealed his true identity as a traffic cop. While he was working, he pretended to be someone else in order to give himself the air of authority he craved.
But even so, his coworkers were aware of his generous nature; nevertheless, until he was caught on film, they were unaware of how unpredictable he could be. And no one had any idea until that point that he was capable of doing something that could have been captured on camera.
