Malfoy pushed his own chair back and made a show of helping Hermione up.   After he'd escorted both women to the door, he stopped when the manager made the mistake of letting out a small, smug sniff.  Then he dropped Hermione's arm and lunged at the man.  Before he could dodge out of the way, Malfoy had his hands fastened around his throat and had begun to squeeze.   The man struggled but he was no match for the vicious pressure that had hold of him and, before a full minute was up, he sagged into unconsciousness.  Malfoy let the body drop and kicked him with a violence that surely broke several ribs.  Then he brushed his hands against one another, examined his nails, and held the door.  "There is a wonderful curry shop around the corner," he said.  "We might be a little overdressed, but the service is much better."
