Does the idiom "I'll take that under advisement" in a non-legal context always (or usually) mean "I'll ignore your advice"? i.e. is it a polite (or not-so-polite) way to snub someone? For example, the following quote I found on IBDB, which is from the movie Die Hard (emphasis added):
Hans Gruber: [after bad guys hit police ram with rocket]
[in radio to bad guys]
Hans Gruber: Hit it, again.
John McClane: [in radio to Hans] Hans you motherfucker, you made your point! Let them pull back!
Hans Gruber: [in radio to McClaine] Thank you, Mr. Cowboy, I'll take it under advisement.
[to bad guys]
Hans Gruber: Hit it, again.
