Keep Your Grubby Hands Off My FOOD *UPDATED* *AGAIN*

I just went into the kitchen at work to check on the state of my salad fixings. I bought a container of salad, and brought in smaller containers of the toppings to keep in the fridge for a week's worth of lunches. Imagine my boiling rage when I discover that someone has INTIMATELY TOUCHED my food containers.  The container which held my lettuce was OPEN and two of my toppings containers where placed INSIDE on TOP of the lettuce. The lettuce underneath it was wilted and disgusting. I am so FLIPPING PISSED OFF right now I cannot even tell you. I understand MOVING things around to make more room for other stuff. I have NO PROBLEM with that. But OPENING, OPENING someone's container of food? WHO THE FUCK DO YOU THINK YOU ARE??? And it is not as if the shelves in a COMMUNITY FRIDGE are exactly CLEAN. So whatever nastiness was on the BOTTOM of my two containers from sitting on the shelf was transferred to MY FOOD. MY FOOD.   My LABELED food. Hence how the culprit knew the items went together.
I posted a note on the fridge. Sans the swearing. I'm awaiting the lunch time back lash.
Where are people's manners? Who does shit like this? WHO?!?!?!

**UPDATE**
The Culprit wrote me a note back, but then removed it. A co-worker told me what it said since I only noticed  that it was missing AND that there was blue Sharpie marks where it  had been hanging.

"It was already open and wilted."


Well of COURSE then! That it an open invitation to do with it what you will! TOUCH AWAY!!!! No need to be HELPFUL and maybe close the container! Heck NO! Add more stuff to it! Rearrange away!!!
BE MY GUEST. Contaminate my food with fridge shelf dirt. It'll put hair on my chest. Just where I need it.

SERIOUSLY Person? SERIOUSLY? I am assuming you saw the error of your ways and hence removed the note after you wrote on it. I can only but hope that is the case and you didn't just chicken out and remove the note for fear of being found out.
Be aware however, I will be checking trash cans tonight after work, because I have a fair good idea who you are, Mrs. Nosey.

**** I was unable to locate the note. I still have no concrete evidence that Mrs Nosey is behind it. But I still harbor my suspicions.******
