Ignorant parent

I hope I can still hear okay. I just had a woman come in here with a little boy. She let's him bring a whistle in here and blow on it the whole time she's trying to talk to me. They go outside with my dad to look at the car. He takes his whistle and beats on the car with it, runs around the parking lot, and of course, comes back in here and blows some more on the damn whistle. The mother may have told him to stop once. No wonder there's so much behavior trouble in schools. It starts with parenting. I doubt my Mom would have let me bring a whistle in a store or a place of business and be so disruptive. I feel like my ears are going to start bleeding any minute now. I bet that's why she backed into a telephone pole. She also asked if we had a payment plan for her $500 deductible. In the words of another ignorant customer, "Story of my life."
