I was not there when this happened. I don't know the tone of voice actually used or the exact words, but I will relate it as it was told to me.
BG: We work in a very large facility. It is shaped somewhat like a four leaf clover with the office (O) in question situated just a little left of center (where all the leaves come together). The four areas (A), one in each leaf, are approximately 200 yards in diameter. There are then four stations (S), one located in each of the four areas.

Some of my coworkers work one in each of the stations. Every morning, we meet in the office before heading to our stations. Fergie (the one who told me what happened) brought in four plates of cookies, one for each station. Two of the other coworkers took their plates graciously. When Fergie showed Mouse hers (I'm not sure if she tried to hand it to her or what), Mouse refused (again, not exactly sure how, whether verbally or non-verbally), but she did say that she didn't want to carry the plate all the way to her station. That means that the person who takes over her station on swing shifts would also miss out on the cookies. Fergie tells me that was all Mouse said before turning away to go to her station.
I do know that Mouse carries nothing other than her lunch box to her station every day. I have seen her carry much more than the weight of her lunchbox, too, so I know it wasn't a weight issue. I also know that Mouse doesn't have any food allergies or intolerances as I have eaten with her a fair number of times.
I say Mouse was quite rude. Fergie doesn't know what she should have done.
