Okay, I just noped the fuck out at work. For backstory, I work at a doctor's office in an upstairs apartment for security. My boss was in another at the time when my other co-worker's phone rang. A friend of hers who she said she hadn't seen in over three years was downstairs. She told our receptionists to let her up. Immediately I freaked out. We obviously can't just allow randoms into our office. I ask if she was really coming up but I could muster more courage than that.
As soon as this woman comes up it's clear that she is NOT sober. My coworker knows this person as they dated her brother, who passed from addiction. And it's clear that this woman is also struggling with addiction.
Come to find out she came for money and a ride. She sounded desperate.
I'm afraid now that she knows how to get to my coworker and inside the building, she may come again asking for money, or because it is a doctor's office she may try robbing the place. I'm scared and no longer feel safe at work what should I do?
