Fire alarms at 5:30 in the morning = NOT COOL
Next time there's an alarm, I'm plugging in the soldering iron and sticking it in a pile of something flammable. Because they just made me stand outside in the wind and cold for fifteen minutes wearing nothing but pj's and a thin housecoat, just so firemen could come and say "lolz nope there's no fire haha!"
So. Thinking about running fire drills in the middle of the night when it's freezing cold outside? Think again, unless you want a little more than you bargained for.
