Here's a scenario for you:
You're in line for the cash register at a really expensive boutique, and you overhear the young girl in front of you tell her friend she's going to be buying a new pair of pricey shoes using her dad's credit card. What do you do?
For most us, the answer would probably be something along the lines of "absolutely nothing" because hey, that's none of our business. Good luck, kid.
But for one woman, this exact situation posed such a pressing, moral dilemma that she simply couldn't bite her tongue and just had to do something about it.
