Offer to pay him for the missed lessons, maybe thats his gripe, 2 lost hours?

What a wounder, i bet your feeling really down
What you could do, is drag scotty down to the nearest used car centre and pretend to want to buy a similar model car (Corsa..metro, micra, whatever it is) and Scotty can show you round the oil, water etc... Then move onto another showroom and you show Scott where it is so you know youve got it

Dont worry too much.. nerves are the biggest cause of failure for sure.
