Well from what we saw that mistake didnt cost them any additional sales. As if they had been about to sell to someone else then had to stop because they couldnt do it because of thw exclusivity clause she'd made, you can bet your life that would have been shown, and the team won.
It was a bad mistake personally for her, and if her team had lost would probably have been her fired for it. But it didnt end up being that bad to fire her from the winning team.
