Where is the coach? Aren't they paying the coach to, I dunno... coach them? I think, in almost every case, you can't blame a student for any mistakes in class. The buck has to stop with the instructor (as long as the student is following instructions, and even then it's the responsibility of the instructor to kick them out of the class if they don't). Anything bad or wrong being done in the class, or not being actively worked on under supervision, is due to a lack of proper instruction.
I have just got two of these hats. I find that they are very good for practically punishing bad habits but not punishing the student.
