I've never left the ring in disgust. She never got any harsh words or nagging; we simply walked back to the crate completely neutral. You don't have to be negative for the dog to figure it out.
I've seen many dogs over the years build a behavior chain of I break, my person comes back, we sit again and this time I stay and we go.

Agreed, Gina!!!!!! For a long time my Rumor broke every start-line. I did the hand-feeding program and she had to wait before being released to her food every feeding and lots of other games and things and she just drove both her and I crazy because I would try to lead out and after I took one step she would be 3 or 4 obstacles on course barking because she wasn't getting any direction.
But since she would rather run than eat a raw steak, the final break was not letting her burn the adrenaline. Break the line, I calmly tell you no, we collar up and quietly walk to the crate. No judgment, no scolding, just go crate. Sure didn't take long for her to realize, no obey=no play. Now we do 20 runs a weekend, give or take, and she sometimes breaks one, often none. And on that occasion, we make it a game to go back, sit, and go.
And I used to face her and walk backwards saying stay-stay-stay. Now it's become stay, lead out, good girl, go!!!!! No stress!!!!
