The canteen at work has PIR sensors in the ceiling that detect movement and hence turn the lights on. They turn off again if no further movement is detected in a certain time period. Great. Very eco-friendly.
Except sometimes I can walk the length of the room, some 40 feet or so, and remain in darkness.
It doesn't always happen but it happens enough, to me, to be classed as semi-regular. And since it doesn't seem to happen to anyone else, do I even exist?
+1 kudos point for naming a coding language that supports (NOT) EXIST (only 1pt because there are loads).
+10 kudos points for irrefutable proof that I exist.
