You seemed to handle it well. I was in a major retail chain store a few weeks ago with my H and a child was having a full blown mega temper trantrum over not getting a toy she wanted. She was screaming at the top of her lungs and crying so loud that you can hear her through the whole store. The father put her in a shoppping cart a wheeled her outsid to calm her down. Her mother on the other hand? She bought the toy that the child was screaming over. When I hear a child act out that way I try not to think the child is unruly. I wonder if there is some sort of emotional/developmental issue. But that night...it was simply the child wanted the toy and when the father tried to defuse the tantrum the mom just set it up for it to happen again if the girl didn't get her way again.
