From now on you are banned from the practice facilities. You do not touch the weapons rack. You do not train in the studio during off-hours. You do not set foot in here while I am teaching a class. You do not ask older students to teach you. I don’t need you causing any more trouble in my studio. Now get out of my sight.”
Damn. And you call yourself instructor? You're not just a racist; you're a piece of shit.
