Don't leave your special cookies or shots where norms might consume them.

A friend left her brownies in a Tupperware in the fridge at work. The colleagues decided to help themselves (good people, so I assume with the intention to replace). There were some rather unfortunate outcomes including hospital visits.

Please learn from her mistake: don't ever leave drugged food where other people/minors/animals might eat it.

How many times do I have to bake laxative cookies before people understand if it's not theirs, don't eat it?
