Give your opinion on a person named Potter and indicate that you had a bad experience of working with him, describing him as a smug, arrogant, supercilious, condescending jerk.
At the end of the day -- by his own admission -- Potter got what he deserved. As one, who once had the misfortune to work with this man, I can say, unequivocally, that Potter is a smug, arrogant, supercilious, condescending jerk.
