I don't want to sound petty as in the grand scheme of things, milk isn't an expensive item and maybe I should leave this be, but it's really starting to grate on me...
Work in an office with around 30-ish staff, the majority are on shift work including weekends so people are in & out a lot. I work standard hours 4 days a week. The company provides tea & coffee but staff bring in their own milk etc. I buy a large filtered milk every month as it lasts and I only have a few cups of tea a day so makes sense.
However, over the last 6 months or so, people will ask me if they can 'borrow' some milk. I would never say no to someone asking but they NEVER bring in their own milk or buy one to replace mine that they've used over the weeks...
Today, I brought in a brand new milk, name on it, placed it at the back of the fridge so hard to find, and I've just gone to make a cuppa and it's been opened without asking, and a 1/4 of it has gone!
How do I word an email to my colleagues (if people think I should) that is polite and doesn't sound too petty?
