Whatever is/was an 'Office Simulator'?
It's where you get to practice drills for No. 1 stapler failure, a flashing low paper clip caption and the like in relative safety. Or in my case, try to chat up the female Flt Cdr from the other flight who was playing the role of troublesome baby Fg Off during an interview (and to her immense credit she played along with it!)
I think it did have a serious purpose though, it allowed you to perfect the art of getting the brews in in a safe environment before being let loose on a merciless crew room!
