Today is my birthday, and a co-worker brought me a small cake. I figured I'd share with my fellow administrative assistants, so we'd cut the cake and had put the lid back on, and it was on my desk.
A professor wandered through our office, said "Oh, hey, cake!", lifted the lid, cut two huge pieces and said "I'm not going to eat it, but I'll take my kids some.." and walked off.
We were all kind of speechless about it. This professor always does stuff like that. She will take half of a leftover pizza for her kids, big chunks of cake, cookies, and so on, all without asking or being invited to take any.
And you just sat there and watched?! Anyone trying to steal cake (or any baked good) from me had better be prepared to draw back a stump!
My former coworkers got me a lovely cake for my birthday. They held a nice little party for me at lunch. There was an 8-inch square of cake left, which I boxed up and planned to take home with me. About an hour before quitting time, one of my former coworkers (whom I will not miss at all) came in, opened the box up without asking me and slices the cake in half, saying, "I'll just take this home to my kids." Now, if she hadn't already had some cake at the party, I might have let her get away with it. But she was notorious for showing up hours after a party, looking for seconds and saying she was taking extras home for her kids.*
I stopped her and said, "I'm sorry, I was planning to take that home to my family, but you're welcome to the chips or other snacks." She pitched a huge fit over it an tried to rally other coworkers to support her claim to the cake, since the whole staff had gone to such trouble for me and I "owed her." I double check with my closest friend on staff, who confirmed that SS Cake Claimer hadn't brought so much as a bag of chips.
* I strongly suspected that she, like most people who "take food home for their children" are actually eating the food themselves and just don't want to admit that they're eating more.
