To start a Vendetta against my coworker over this

[DoubleNegativePanda]

I came back from lunch to find my coworker sitting at the kitchen table using my personal tea mug. We all have our own mugs, and we know whose is whose. I lightly said "hey, that's my mug" thinking I'd poke her a bit but I wasn't really mad. Yet. Until she said:

"Oh I know, but it's the biggest and I wanted to fill it all the way up with bone broth"

She filled my tea-only mug with disgusting collagen-y bone broth and heated it until boiling in the microwave. She clearly knew from my expression that this was not okay and hastily offered to handwash it to make sure it didn't stain or leave a film, but AIBU to be really pissed off? Who does that? Use your own cup and fill it twice, but don't ruin mine! Because it may be ridiculous but I feel like my lovely favorite mug is ruined for tea.

After reading the op I scrolled down to reply that you obviously now need to piss in her mug, and found I had been beaten to it by other posters. This is why I love mumsnet I guess

Drill small holes in the bottom of her favourite mug.

I had a colleague take my personal bowl once. The one I made my porridge in daily. She used it to soak her new belly button piercing! I went looking for it and there it was on her desk, half filled with boiling water and her belly ring in there soaking. I don't think I've ever been as furious. I marched her to the supermarket next door to buy me a new bowl. Who even does that at work anyway! I'm still a bit mad now and it's been about ten years 😂

Get one of those mugs with a plug on the bottom that you pull out and keep. That way no one can use it for horrific soupy concoctions.

It's just stock though.

My parents used to make stock from bones. It stank the house out. So YANBU.

YANBU are mug but YABU for using the term coworker.

I'd steal her cup, use it as a kitty litter scoop, rinse it & pop it back. Sit back all smug like 😂

I'm just sorry you are female OP. Well, I'm assuming you are? You could buy her this wee beauty.

I’m glad I’m not the only one who read it as vienetta.

Same

Who TF calls stock “bone broth”? Does she call meat “roasted flesh” Can’t she dress it up and call it something suitably palatable like err...soup?

I couldn’t use that cup again. I’d be forever smelling bones in my brew

The people that are saying "it's just stock" just don't understand. It's jiggly jelly stock that's been boiled in an earthenware mug that has only ever had tea in it. That weird taste is never coming out.

A tea mug is for TEA.

I once had a colleague who always made a beeline for another colleague's personal mug. ( It had her name on it) The mug owner got so hacked off that she superglue the mug to the kitchen counter. Childish but very satisfying when mug snatched tried to snaffle it!

I would ignore those that are posting "it's just broth" or "its healthy" as they are the type of people that would do this.

Fart in her mug.

Your mug will never be the same again

Bone broth is stock. The fact it has a bit of gelatine in it is neither here nor there. If colleague has heated up chicken soup it would be no different.

I would be pissed off by chicken soup. It just makes it all the more gross to me because I think jiggly stock is specifically rank. But any sort of soup in a tea mug is WRONG.

I did come in to work this morning and looked at the mug and it's been scoured within an inch of it's life...it may have survived and it will depend on whether I can forget the smell of the "just stock" and keep using it.

I must have had a really scary face on for how seriously she washed it.

@BadgerWithSprouts Flattery will get you everywhere!

Buy her a 50p plastic jug.
Hand it too her with an Xmas ribbon on...

Are you basically saying she drank a whole mug full of gravy?

This.

Why the fuck would someone need to heat up a mug full of stock at work

Was she making the office Christmas dinner? Drinking the stuff neat?

Who on earth takes a mug of stock to work to heat up?

Tell her that you soak your teeth in your mug !
