Finish with her

The gypsy girl glares at you. "I'm going to kill you!"

"You will not harm me, nor tell anyone your actions today were not your own idea. As far as the mud, don't try to wash it off or have anyone do it for you for at least a two days. then go back to your fellow theivish gypsy clan but first prance around the perimeter of town while you smack your arse as hard as you can and whinny like a horse so the sun can dry that mud."

The gypsy looks totally defeated. She lets loose a loud whinny then gallops off, smacking her ass as she headed for the edge of town, making a complete fool of herself. The crowd laughs and a few children follow her, mimicking her and throwing mud at her.

You smile and head back to the tavern. The gypsy's clothes and jewels, fake or real, have been pilfered by the crowd, but you have the nice dagger as a memento.
