Speaking of being told what to do.
I used to work out at a club with pro body builders.
I was on a lat pull-down apparatus when a muscle head tapped me on the shoulder and said, "Are you done?"
I said, "Not yet."
He leaned down to my face and said, "You're done!"
Note: He had a huge square jaw (Arnold Schwarzeneggeresque) ...indicating a steroid user...and I knew that they have a huge temper problem.
I got up and walked away. Smart of me, eh?
