I went to a small liberal arts school where all the professors were fantastic and took us out for drinks, had us over for bonfires, and were always willing to work with us if we needed to reschedule an exam. It was incredible. That being said, there was one instance when I sent out a campus wide email about ordering zoology department t-shirts. One of the theater professors (clearly someone with a bit of a tendency towards drama) emailed an absolutely snotty,horrible email threatening to revoke my ability to send campus wide emails (which only club presidents and department board members had). Personally, I like to meet challenges head on, and I think that if you let someone act like an ass to you once you are more likely to let others treat you poorly as well. So, I emailed the professor back and told him that he taught at a liberal arts school and he should embrace that and encourage it in his students by buying a t-shirt. I never heard from him again. Any way I look at it, I think it was a win. I stood up for myself (an didn't stew about the situation), and I might have reminded the professor that he should be tolerant of students particularly when they are active in the campus community.
