well yes you can get suspended from any school including hapkido for disobeying their rules
yes. dont throw sand. this isnt the movie bloodsport.
I smell bs.
I got in trouble twice this month for using the Coon sand while sparring and my master said that I would get suspended for a month of lessons if I did it again. I stopped bringing the Coon sand to practice but he thinks I'm hiding it in my clothes. Can I really get suspended for this?
