I came back from Lunch today (I spent it at home) to find a whole mob of people from the building I work in out in the street. Turns out there was some smoke in the building.
It also turns out it happened somewhere on our floor! They think it was a transformer that just got too hot and started smoking, and then set off our alarm which set off the building’s alarm.
The alamr on our floor has been going off for about an hour now so we’ve been spending a majority of our time outside talking ;)
