Turns out, I was right.
I'd probably be bad at dealing with auditors if they use idioms. "I'm sorry, what does that mean? I swear I speak English as a first language... I'm just sheltered..."
My dictionary doesn't have this one either...
If someone gives you a nickel tour, they show you around a place. ('Fifty-cent tour' is also used.)

Nickel Tour
My Score Card for this idiom:
Able to be understood initially?: yes
Able to be understood once explained?: yes
Fifty cent tour... haha. It's impossible for me to say that without turning it into "fiddy cen". Oh, pop culture! How influential you are.
Yours truly,
A sheltered American
