“Bullet in the Brain” by Tobias Wolff

And then the tellers stopped what they were doing, and the customers slowly turned, and silence came over the bank. Two men wearing black ski masks and blue business suits were standing to the side of the door. One of them had a pistol pressed against the guard’s neck. The guard’s eyes were closed, and his lips were moving. The other man had a sawed-off shotgun. “Keep your big mouth shut!” the man with the pistol said, though no one had spoken a word. “One of you tellers hits the alarm, you’re all dead meat. Got it?”  The tellers nodded.  “Oh, bravo,” Anders said. “Dead meat.” He turned to the woman in front of him. “Great script, eh? The stern, brass-knuckled poetry of the dangerous classes.”
