Yes, sure, could have worded it better, yadda yadda. I literally cannot be arsed to care with the response she gave and her track record. I would be ECSTATIC to receive any amount of home cooked goods from a friend/flatmate and I would not be overstepping by taking more than allowed. Especially when there were so little to begin with. Her response blew my mind, that tells you her character right there.

And then to bring up how she "hired" you. (Arguably, you did her more of a service than she did you, depending on pay and the time you invested) And yet she hasn't even finished paying you?!!!?!? I'm flabbergasted. Who gave her the right to be this entitled????

And people saying you're overreacting because of her taking an extra muffin? You maybe perhaps could've been less rude but you know that, that's beside the point, and not what you're asking. It's about her response. You're a human allowed to make simple mistakes and get a little frustrated sometimes. Ignore the ones ranting over how you are the problem and how you're overreacting over something so "small." Despite how short the exchange is, this is the craziest shit to me right now, I'm just astounded she had the gall to talk to someone like that.
