Flight training centers aren't really better if you are looking for relaxed and laid back. Most of the instructors there have more students than they feel like they can handle, and often have issues with getting planes, etc. In addition, they are in the middle ground between the school's management and the students who are paying for training. It's often easiest to vent at students since they are LESS apt to leave or switch in this environment. By the way, this is from personal experience as both a student and now as an instructor. Stand up for yourself and find someone you can work with.
