It's a martial arts school, not the government, you're not there to serve them you're there to improve your skills. Do what you need to do to make yourself better, you didn't pledge an oath of faithfullness or anything (unless you did which would be al ittle weird). I'm sure they have plenty of students so hwo cares?
