service for a rally team sometime and all of a sudden all of the things that have gone wrong with your car or what you did with replacing the rack seem minuscule in comparison
example: Driver hears "clunk" coming from front end after running the last satge of the day, decides that the front control arms need to be replaced. You and another monkey who are servicing spend an hour changing the control arms, at 1am.
the "next morning"...really two-three (I cant remember) hours later, your driver brings the car to Parc expose and tells you and the monkey who helped you change the control arms "the clunk is still there"
"Lets change blah, blah blah" at the next service (you have 20 minutes)
Its all relative man
