Hurry Up!

In 3-X "One Shift More", after the line "But they've been waiting for so long", if the player doesn't press the last beat, the Politician's urging can be heard.

"Oh, come on, make your move! Hurry up!"
"You can do it, come on! Hurry up!"
"Any time. Now, come on! Let's go!"
"Make a move already, would you?"
"Oh.... bloody hell, hurry up already?"

After that, he'll press the last beat.
