Male voice

As I’m pacing around working the phone using a headset, so I can use my hands. I notice in the staircase area someone is saying something. Definitely male, not angry more like making a comment. I'm used to my co workers roaming around working on the various levels of this big old money pit. Then it hits me, I'm alone, all 9 exterior doors are locked.

Personally I’d rather it be now, versus 3 in the morning!.
