You walk away from a jerk like that and you are only encouraging him to pull the same stunt again on someone else. First off, my hunt has been ruined, and I' ll be darned if I walk away without ruining his. I' d pick myself up and plop down right beside him in the wide open, crack my lunch, have a coffee, play my radio, have a ripe old dump etc, etc, etc til he got the picture.
