Is AUTHOR wrong in the post ? POST : Okay, this will make a lot more sense after you've read this (duh).
So get ready because I won't make a "tl;dr" ;D

Backstory: 
Two days ago my company installed new firealarms  in our office building. 
In January we began building a second office complex right besides 
our main facility. That new building has no firealarms installed yet.
I later figured that you can't hear the alarms from the main building there.
We're also renovating the main building (where I &amp; said co-workers work). 
Since Monday the toilets in our complex are being renovated so we can't 
use them.
Fortunately the toilets in the new building work fine, so we just go there
for now...

Enough backstory? Good.

--- Here we go... ---

So, this happened about 4 hours ago. I was working on my desk
and minding my own business when suddenly the firealarm went
off.

At first I thought: 
"well, the firealarms were just installed, maybe it's just a minor malfunction."
However we took the alarm serious and evacuated the office building.

While we were on the way out I noticed that two of my (female)
co-workers (let's call them Abby &amp; Shelly) were not in our "evacuation group". 
I remembered that both of them went to the restroom literally 5 minutes before the
alarms went off. It takes a couple minutes to get to the toilets in the
other building so I figuered they'd still have to be there. Since there are
no firealarms in that new building (and there's only one way out) they
could've been in great danger.

There was no visible smoke or fire, which was good. I didn't see 
Abby &amp; Shelly on the way there or around the restroom so I opened the door...

Abby stood right behind the door and looked at me in shock, while Shelly
was washing her hands - she too looked shocked.

I told them without further ado that there might be a fire in the building 
and the alarms went off. I also told them that we have to get out of there.

They both got very angry at me for opening the women's restroom without
any warning. And they kept telling me that on the entire way out. They said
"there would be consequences".

When we finally got out Abby and Shelly went for a group of other women
and told them "what I did". But the group didn't really understand why
they were so angry, after all, I only tried to help...

We all got to take the rest of the day off...

Moving on...

It turns out someone left the kettle (water cooker) in the break room on 
which resulted in an electric bypass. The kitchen counter and some chairs
burned down. Gladly the fire fighters stopped the fire before it spread in
the building...

Anyways, if you've made it to down here let me know what you guys think...

EDIT: Can't believe this got so much attention.
So my boss phoned me this evening and told me "Abby &amp; Shelly" spoke to him about the "incident". He too told me that their reactions were absolutely insane. He actually complimented my "bravery". 

Thank all of you for responding to this post. That's why I love Reddit.
