Your kids are destructive, deal with it. Sort 'em out!

This woman comes in with 3 lunatic children and one of the boys comes up to the counter and in his classic I-have-no-consideration-for-the-hearing-of-others 8 year old voice yells, "THIS GAME DOESN'T WOORRRRKKK!!".
I cringe and prepare for yet another ordeal.
His mother explains to me that the game didn't work last time and so we she had us repair it in our professional disc resurfacing machine (which completely takes off scratches), and now it still doesn't work. Sounds almost reasonable, sometimes discs are just fucked.

I look at the back of the game disc and, big surprise, I see an unthinkable amount of large surface scratches and child-size finger prints.
"So let me get this straight: You had us resurface the disc for you and now, through no fault of yours or your well-behaved respectful kids who happen to be tearing down full shelves in our game section and laying around the floor, the disc is now horribly scratched and doesn't work?"

She confirms. I stare.
As Drew said, trying to claim that her saintly children were responsible for this would clearly be character assasination.

I put this disc right up in her face and say "now, when we repair games it RESURFACES it, removing all scratches. Do you see these scratches here right now? These came from somewhere. Perhaps your kids are not handling the disc properly?"
She says "No, it was broken even after the machine fixed it"
I say "That maybe, but there were no scratches on it... where did they come from?"

This goes on for a minute and she never realizes or admits to the broken disc being from her kids abuse.
OPEN YOUR FUCKING EYES, WOMAN.
