I recently trained in a dojo in Thailand. I had no Gi, so wore shorts and T shirt. The sensei put me on the floor and pressed down on my shoulders, leaving my arms free.
I didn't know whether to free myself, which would have been easy for me to do. Instead I just accepted his move..But I felt as a teacher he could not have possibly made this error. I left and have not been back.
As any one else been in this situation and what do you think is the correct course of action to take?
