On this certain occasion i was starving and was busy so i hadnt thought about lunch yet, as i am thinking this my fellow worker says im just going to go get my food, i reply what do you mean get your food? .....he replys I have already ordered i am just going to grab it......i reply well I'm fine thanks... I am enraged, I cant belive he did this. His retort is oh well you never get something? I am even more angry. I say OK mate AND procede to tell him that there is unspoken rule and we dont just go get our own lunch, you ask us all if we want to order anything, even if we rarely do!!!

AITAH for wanting a family like enviroment in the workplace, I have explained how divisive his decison was and I am not sure i can get over it
