I am not endorsing trying to catch someone with their proverbial hand in the cookie jar with their pants down peeing on the floor, rather to show up when things are operating "normally" and not tweaked to impress the observer.
I don't want to see people embarassed or put on the spot, but I'd like for those that get the VIP treatment to get the reality treatment.
I've experienced both types of scenarios played out when I was in the Army. Often durring a training exercise, the "Brass" would show up and observe. Some would do so quietly, others would try to take over and show the young officer how it is "supposed" to be done. The ones that had the biggest impact on me jumped in and helped and offered advice without being overbearing. I once had a General fill in for my radio operator. That was humbling and impressive.
All I am suggesting is come to the operation and jump in and help. You'll learn a lot more than arriving to trumpets and red carpet.
