when does setting time for office hours and then not showing up become a norm? It's kinda wage theft, or maybe he thinks we are paying to just wait for him to come to his office which he never does during office hours. 

Also, the one good review would be from him or a TA. 

WORSE PROF I EVER HAD. BRO NEED TO BE RETARINED HOW TO TEACH.
