what to do if new students seem like they are there to beat you or your students up? sometimes people who like to street fight go to a dojo to test their skills see if they can take on a blackbelt or are there just to hurt someone. maby a street fighter been in 20+ streetfights and a blackbelt maby have never been in a real fight. just curious who to deal with new students that want to learn martial arts just to beat people up weather its you or someone else ?
