I have been to yoga classes where the teacher is harsh, scolds the students unnecessarily and generally acts like a bully. I try to avoid those teachers, and to be fair, they are few and far between in my experience. And usually there is some explanation for their behavior — everyone has a bad day once in a while.
But what do you do when the yoga student is the bully? I have seen yoga students fight with one another over mat setup or the temperature, but I had never seen a student bully the teacher — until the other day.
