Or just...normal?
In work, largish kitchen but only one microwave and a few of us have things to heat. Everyone lines their food up as they go in as a kind of queue, there's something in the microwave going and everyone sitting at tables waiting to use or already eating.
The food in the microwave finishes, beeps and after about two minutes of waiting and everyone looking at each other and asking 'is it yours' we all realise canollini owner isn't around.
After another minute of waiting the next in line removes the food, puts it on the side (where it madly bubble away because superheated) and puts her soup in to heat.
After ten minutes, canollini owner finally returns and starts off on a massive rant about how it's disrespectful to touch someone else's food, even if it's sealed, and everyone should have waited their turn. Canollini owner then gets the hump and storms off, still ranting, saying they are going to complain when soup owner apologises and then her and myself point out that it's a waste of time to sit around and wait and she should have stayed to keep an eye on her food.
Everyone else just ignored us all. I'm sure (or at least both soup owner and I were but now we're a bit confused) it's not unreasonable to remove the sealed food and put it on a plate to one side, but soup owner and I are in one department and everyone else- canollini owner and all those who ignored the whole thing- are in another but did we make some big faux paux?
