All right, you amazing brainy people laying the new plaster on the floor of the corridor outside pharmacy: how did you THINK I was going to leave the place? Did it not occur to you to ask if I was STILL THERE BEFORE YOU STARTED??
I'm glad I have a good imagination, and worked out how to turn the alarm on by sneaking out through the front door. >:( Just had to tell security they needed to go lock the main corridor again.
What's that about common sense being a superpower? Bah.
