Yup, everything about that phase of the course was fantastic. My first job out of IOT (holding before BFTS) was as ADC to a 2 Star (AO Maint), who let me see everything (and I do mean everything) in his In tray for 4 months - with these two experiences I learned a heck of a lot. I have had friends who were everything from plant managers and CEOs to Headmistresses and Government come to me with admin problems. I apply what I learned, advise them, and it has worked every time.
The example you describe was typical - find a way to provide people a service and apply the rules.
I liked the way some stude in the office sim would occasionally have naff all to do, sometimes for hours. Very realistic.
p.s. Also learned that OC Money, OC Catering, and OC Regiment are the first people you invite to be honorary squadron members of your fighter squadron - remarkably useful people to know.
