A friend of mine was having a similar problem when he flat shared a few years ago. In the end he decided to take the perfectly reasonable step of leaving some cat-food sandwiches and a pissed in bottle of coca cola in the fridge, both were consumed.


Alternatively you could just have a word when everybody is in the same room.

The problem with milk thiefs.
If you ask them not to steal other peoples milk. They will say without a shadow of a doubt "I never have other peoples milk and I would never take milk that isn't mine". Milk theifs are like peadophiles they don't realise what they are doing is wrong.

Ah
Go for option A then.

this is why
when everyone is in the room, and you just noticed your milk went down, you randomly announce "Yay, the milk thief used the sabotaged bottle!"

Just leave it at that...no need to go further...yet.
