Guys not curent on code? How can you tell?

Let us imagine a typical scenario: The inspector sees something, and says "that's wrong." Now, what's the sparky going to say? Take your pick:

a) "No it isn't you ignorant paper pusher!"
b) "Really? When did we start requiring....?"
c) "Gee, I didn't know!"
d) "Where's that apprentice?"
e) "I must have forgottem my smart pill that day" or, finally,
f) "We've always done it that way"

I suspect that even the guy who has the entire code memorised isn't going to use choice "a".
