My advice... ​ Look that AH in the eye and ask "What is it about me that makes you feel so insecure about yourself, that you have to try and intimidate me...Would you say or act like this if I were in a wheelchair. Perhaps you may want to think about why you feel so helpless and insignificant in your view of yourself? ​ Basically spin the ego, onto themselves... ​ Don't say it with anger, just ask the question in your normal tone of voice and don't give a second thought if you stutter during your delivery.
