Maybe a time-out, in a submissive position, and her nose in the corner... but I'd be there watching... and maybe talking.

But never ignoring her. Too cruel.

And never something I enjoy doing to her, regardless of her like or dislike. Too likely to find excuses to punish her... when I know she'd encourage me do it for the pleasure it gives me... so why associate it with punishment?

No.. the absolute worst thing I could do is let her know I'm disappointed.

But, I'd definitely let her make amends and gain forgiveness.
