Yep, that happened to me in a DC airport. American service is horrible.

By contrast, when I was trying to board my plane in Tokyo to return to the US, I again forgot to empty my water bottle, and was already through the line. The woman just asked if she could dump it, and she did: they had special containers there for the express purpose of dumping people's disallowed liquids. Of course, American security can't be bothered to implement a common-sense measure like this.
