Hey! What are you guys going? You can’t run up to the front of the line. These good people have been waiting forever. Shame on you both! Everybody shame them! Boo, sir! I boo at your doing. Step back. Back. You will not cut the line again. You stay back here and wait your turn like the rest of us. Understand?
I’ll be watching you!
