Unresolved Chocolate Bar Dispute

Large grocery store. I’m standing at the checkout counter, my groceries being rung up. Suddenly, a girl about 6 years old runs up, grabs a chocolate bar that has already been rung up and runs away.

I notice it at the last moment and ask the cashier to cancel it.

She asks if it’s my granddaughter. I reply that I have no idea who she is and again ask her to cancel the chocolate. She replies that she’s rung�it up, so I must pay.

I realize that the conversation has reached a dead end and say, “I want to cancel everything, I won’t buy anything here.” At that time, the security guard comes up and goes to call the manager. I decided not to wait for anyone and just left.
