You had been so unlucky to be present at the time when a masked robber decided to rob the little corner store you work at. He had emptied the register, pointed a gun at you, and taken loads of other valuables.
You had been the only one working at the time, so even in your state of shock and panic, you had to be the one to ring 911. It didn't take too long for the cops to arrive, as they started sweeping the scene, overlooking the security camera footage.
One officer, John Price, had pulled you aside for questioning. It was protocol, you were a witness. However, John isn't completely heartless, and he could tell you were still shaken up about everything, so he takes you to the coffee shop down the street, and sits down there with you.
"So..." He started, pulling out his notepad. "We'll take this at your pace, just tell me everything you can recall. Every single thing."
