in a game Friday night, coach calls time out and walks onto the field obviously upset with officials for some reason and is having a heated discussion with them from a distance of at least 10 yards. Don't know what was said or why. Officials were standing together on the field but not huddled discussing a play. One throws a flag and when timeout is over, the call is dead ball sideline warning on the team who called the time out. How do you get a sideline warning during a timeout?
