[kjc0123]

What is the meaning of "Don't get me started" in the following sentences?

The agent held up a passport picture of Robert Langdon. "Was this man in your bank tonight?"
Vernet shrugged. "No clue. I'm a dock rat. They don't let us anywhere near the clients. You need to go in and ask the front desk."
"Your bank is demanding a search warrant before we can enter."
Vernet put on a disgusted look. "Administrators. Don't get me started."

It means 'I have a lot to say on this subject because it really annoys me. If you get me started talking about it, we will both be here all night'.

[Peter Pedant]

hi Kjc wel come back. I have often wondered where you had got to (in K that is) because whenever you asked a perfectly reasonable question in an admirably polite manner,

some brute could not resist giving you a kick in passing. See one of the threads up above. And no, dreadnought I dont think that there is a Korean translation of DaVinci code.

I think it is perfectly reasonable to ask the questions you do, and I at least for one welcome them,

Welcome back Kay-jay!
