Fire Drills
Fire Drills are regular part of any commercial complex these days. They announce it is a "drill" and not a "real emergency" - and people exit via the staircase and not use the elevator and return to their desks, once the drill is complete.
Now what is interesting is what people "do" during the time they are outside the office building - If you have not guessed it, they queue up at the nearest coffee shop.
Conspiracy Theory (CT) : When the coffee shops have to announce their quartely financial reports, and they know they fall short of the targets - guess what is it that they do ? - call up the near by buildings and "donate" to some of the businessess' charity/funds and have them do a fire drill :D - a win-win-win situation (business makes money and conducts security drill, coffee shops meet the target and employees get time off from their desk)
