does anyone find this inapropriate but me

k so today in my orchestra class we were sitting there listening to him. and my stand partner was using a cloth to wipe off her violin and i pointed to the cloth and really quietly asked her if i could use her cloth to get the rosin off of my violin and he gives me this death stare and points at me then points and a stool thats infront of the class and tells me to sit up there infront of the class and and he gave me a a lecture infront of the entire class about being respectful when some ones talking for like 5 minutes and then makes me say ten times to the class that I'm disrespectful and that i cant keep my mouth.
i dont think thats really exceptable for him to do that what do you guys think
