Dave - I am having a good chuckle.
I can up you with one. When we had a special group of Ferraris, Lambos, and Maseratis all bunched together as a special group for instructions at our regular TrackMasters program, we were told beforehand that as instructors it would be "advisable" to have clean clothes - not your shade tree mechanic showing up ........ makes sense I guess. And when we were subtly informed that the catered food was not for instructors, we didnt care what they said either LOL!
Suffice it to say the testosterone on some of the drivers were off the chart until I had to call them all back to a special debrief to note that you can't pass three cars at a time without point by especially when you had novices and show-off high intermediate drives in the same group. Of-course the culprits didn't show up. It's just part of their psyche ......
