The point is do you like SPAM sandwichesSpam sandwiches no, I can think of a number of times when the tinned Corn, Beetroot and Spam have been dished up, but nevertheless I accept the food with a smile and a thanks because I know that those Salvo people are vollies just like you and I and probably have no say in what goods they are given.
If we have a problem with the catering at large jobs it needs to be raised through the debriefs and pushed through your chain of command. I think you'll find the CFS Infrastructure & Logistics staff have a very good relationship with the Salvo bosses and can probably request changes if they are given the information.
Having said that I have also had some great tucker from them, those up at Gladstone will remember the great lunches the Salvo guys put on - and cake - oh for that cake again
