My only question is why this counter-espionage sticker was posted above the urinal instead of inside:
Stickers with the number of a hotline for reporting suspected spies have been posted above some urinals. Packs of tissues handed out to troops carry a notice promising a reward of T$5 million ($180,000) for successfully exposing a spy.
Imagine a urinal sticker with a secret message revealed when it detects something specific… I swear I am talking about a real product already and not inventing some crazy urinalysis feature.
The sticker could say “if you’re a leaker, this sticker will reveal a number for you to call and turn yourself in”.
Ok, ok, so my other question is whether that sticker said something like “leaks can kill, call us if you see one”.
