Last night I baked a cake. It was a small loaf cake that my colleagues and I had been talking about and I said I would give it a go. It took me quite a while to make and the ingredients weren't cheap. I brought it in and said to one of my colleagues "Sandra, I finally baked it!, would you like a slice? There's a knife here." Pointing to the table where we sit. As she was cutting her piece a few people stood behind her. I hadn't realised that's what they were hanging around for until I looked around and saw most of it gone. I work with about 100 people and about 75% of them use this staff room so I am not making cake for nearly 75 people when I want to treat the few colleagues that I am close to. I wouldn't mind making enough for everyone if there was only 10 of us for example so not to exclude a few people but not this many! AIBU to think you don't just assume you are entitled to a share of something when you haven't even been offered it? When people bring in treats for everyone they will leave them near the microwaves on the worktop with a note not just a tiny cake on a table! I felt too awkward telling them to leave it alone when they had already taken most of it. I'm annoyed that the people I made it for didn't get any after the effort I made. Lesson learned: keep cake in a locked box at break times when you work with locusts!
