In the movie Hearbreak Ridge with Clint Eastwood, when he's in the bar he orders a beer and takes a drink of it.
Then, he talks to his wife and the camera changes angles.
When it shows him again, the beer is full again (and there's foam on it again).

Clint Eastwood stars as Tom "Gunny" Highway, a grizzled Marine vet of the Korean War. About to retire from the Marines he's assigned to train a group of misfits, and gets one more chance to go to war when the unit is assigned to the 1983 invasion of Grenada.

During the Grenada invasion section of the film Highway's unit is trapped in a house under fire. When their radioman is killed and his radio damaged they have to call back to the US via telephone to arrange for fire support. This was in fact based on a real incident during the invasion, but in real life the phone was used for a much more disturbing reason. A unit of the Army's 82nd Airborne Div. under fire found it could not call in naval fire support because their radios did not operate on the proper frequencies. So they were forced to phone Fort Bragg in the US via commercial telephone to arrange for such support.

Say, does anyone know Clint had a real raspy voice or he did it on purpose for this movie?

Now, that's a good question. I think it's natural. See "Space Cowboys", for example.

btw, I tried to work at Clint's Bad breath Inn in the 80s. They wouldn't even call, they hired everyone when it first opened.

So? That just means that they didn't have any openings.

Good movie but how does this fit into the Western genre?

It shouldn't, Mike. See Adam Bomb's 8/31/07 post.
