They do a job that no one wants to get posted into and are under a lot of pressure to get things sorted. Personally I have found them most helpful, and if you present them with a sensible solution to your problem(bearing in mind you useually have an easier time as you only have one problem on your hands) they will, 99% of the time, go with it. Yep, things get fouled up... but hey doesn't that happen to us all at some point.
