One of the things about the public service is left overs to be eaten after meetings. When I was but a lowly temp in various Queensland public service agencies, the leftovers tended to be open sandwiches or a luxurious range of cakies. On a bad day it would be muffins or chocolate biscuits.
In the Commonwealth, if you get anything at all, you get an Arnotts assortment, meagrely served out at one biscuit per person, with everyone desperately diving for the scotch finger and dreading the milk arrowroot.
In one section I worked in, various policy officers used to bake at home and bring in treats especially for meetings with State and Territory public servants, because we all felt embarrassed at the disparity between what they offered us, and what we offered them (which was a glass of water and an invisible plate of nothing). Until someone got worried about food hygiene, and about the ethics of causing food poisoning in people who had to fly from Canberra to Perth.
I have heard that they serve mini sausage rolls in Western Australia, but I think it's a myth.
