Don't Force It
If things aren't working, don't force it. Some kids aren't excited about wearing a cape, so if just getting one on your lil starts the frustration, skip it and continue with the cut. If you know things aren't going to work, it's totally OK to end the haircut before it's even begun. Pay the stylist for her time and plan on trying it again another day.
