ALA Anaheim: The Late Show

Some speakers deliberately (it seems) begin a program late out of fear it will otherwise run short and as a result they'll be implicitly accused by an audience that it's not getting its money’s worth. Talking to the end also suggests that the speaker had so much more to say but ran out of time. Such a talk has one of two effects on the audience. People observe either, "The subject was getting warmed up, and the speaker just couldn't cram everything in"; or, "At long last that's over."
