Some things I've noticed, that led me to walk out on a couple of schools:

1. Teacher singles you out and calls you out in front of the class.
2. Other student(s) actually laughs/snickers when that happens. and the Instructor allows that!
3. Teacher physically injures you. Could be to make an example of you. You notice the pinches are hard, the take downs are harder. Or the workouts are VERY strenous before the actual practicing of forms and techniques.
4. Instructor actually makes lesser instructors micromanage you.
5. Sensei tells you that "just b/c you said that...re: what is needed to advance, you get to wait another month before I test you."
6. Instructor bullies you, whether physically or mentally/emotionally.
7. Mats are hardly ever used, and gym space is pretty dirty from other classes.
8. You and your head instructor have a clear personality conflict.
9. The head instructor and owner actually have drinks together after class!
10. The owner puts down the instructor, but actually lets the instructor do as he pleases as "he knows his stuff", etc...
11. The instructor says sexist, racist things at class level.
12. On some level, regardless of what you did, he/she just does not like you as a person, and is easily annoyed by your presence.

So these are things that I've noticed, esp. in my last class. If you see them, you need to really walk on.
