Yea, while her and all the rest of the 'staff' were asking to leave they kept being told they hadn't recieved authorization from the higher ups. My wife was their primary payroll person at the time so she said "I'm leaving" and no one wnated to argue with the person who sends the paychecks so she got out of there.
Telling that story to others in the years after I found that was a common thing, the most valueable people to the company were the ones who got to leave first then the "replaceable" people were let go.
Now when something happens at work, be it a drill or not, I break some of the rules and get out of there because I don't know if the security staff is acting in my best interest or in the best interest of someone high up in the company. They might yell at us to get to the right on the stairs or go down a designated stairwell but I don't listen anyore, its unfortunat that one can't trust the people who are supposed to be keeping me secure but its a real issue now after that incident at her work.
