The first thing I heard from this guy, it was in response to one pilot, still at the gate, requesting runway 31 and he told him there would be a delay due to traffic concerns because that was not the usual runway for that route of flight and to call back when he was ready for taxi. This was at 7:50pm Eastern (I saw the time as 7:55 but my clocks can be a little out of whack). After that, and a second request from the same guy for the same thing...the ground controllers patience kinda goes downhill. You can here other pilots chiming in with "Nice guy" and "Shift change". I do wish my controller supported the equipment to capture the clip and post it my self, because this was funny. At 8:00 the controller changes, so I'd say everything took place between 7:50 pm and 8:00pm.
