As I have said umpteen times, I work in a tiny office. Our "kitchen" is a coffee table in the corner of our room with a kettle, an enormous tin of coffee granules we get from the same place we order our office supplies from, and an assortment of teas of all flavours, varieties, and use-by dates. One of these is a box of peppermint tea that I bought.
I buy peppermint tea because I have a bit of a dodgy stomach and we have one toilet with thin walls, and when my IBS is playing up and I'm not in the office on my own, I want to take preventative measures. So I brought in my peppermint tea for these occasions, and I put it on the coffee table with the understanding that this was mine, and you'd no more help yourself to it than you would grab my lunch out of the fridge.
APPARENTLY I WAS WRONG BECAUSE COWORKER HAS LITERALLY JUST SAID, 'OOH, I FANCY A PEPPERMINT TEA' AND THEN JUST FUCKING HELPED HIMSELF.
Like dude, seriously? Seriously??? Rule of thumb: if it's not something that we order and charge to the accounts, like the huge canister of coffee, or something that we take turns to buy, like the milk and biscuits, just assume that if you're not the one who bought it, you should probably ask the person who did if they'd mind you using some. Because I wouldn't mind if he had asked, but because he helped himself to it without even thinking, "hirondelle bought this so I should probably ask first", now all I want to do is grab the box when he goes out of the room later to keep it on my desk.
It was similar when I used to get biscuits, I'd buy them more often than Coworker would because I like having a pick-me-up at about 3.30. I'd put them on the table with the coffee and the kettle because I thought, I'm not going to be selfish and keep a whole thing of chocolate digestives to myself. Or so I thought, before I realised that one day I'd eaten two of the biscuits and yet somehow half of the pack had disappeared.
FEEL MY PEPPERMINT TEA-INFUSED RAGE, GT.
