You should have just punched the tech and ran! (inside joke)No really.... When I first started, I just told them its my first time and they directed me on what to do. Ask them how things work while you're getting your car teched, and don't do anything with out making eye contact first. Don't take a personal if they come off as dicks, its not you... its the 100's of moronic rednecks that have made the officials there think 99% of the racers are idiots 
Here is a small list of things you should or shouldn't do.... maybe others can add to the list:
1) Don't start staging unless she tells you to go by pointing to a lane.
2) Don't start your burn out until you look at the guy near the tree and he gives you the burnout hand sign.
3) Make sure your doors are unlocked, your windows are rolled up, your sun roof is closed or your convertable top is up.
4) If its at night, only run your parking lights.
5) Drive SLOWLY on the return road.
6) Leave the burning out in the pits to the rednecks with trailored cars.
7) Drive slowly in the pit area.
