window person?

[pinkie9]

Do native speakers say a "window person" to mean a "contact person"?

For example:

1. Someone is interested in a product of your company. You recommend that he should contact Mr. Brown, who is the "window person" of the department in charge of the product.

2. How about a case where there is actually a window? For instance, a clerk sitting behind the window of a ticket booth to sell ticket to customers?

Japanese people sometimes use "window person", but I guess it's an English phrase created in Japan and native speakers don't use it.
But I read someone's blog which says the author heard it in CNN news, so I wanted to confirm if it's used by native speakers.

I've never heard it used here in the UK.

I've never heard it either. There are only 3 hits for it in Google, one of which is this thread. There is a blog post which suggests that it refers to the main person you talk to in your company or team, but the blog isn't very convincing.

Not used here.

I would have no idea what it meant if it were said to me.
