DC9-30 CAPT AND ATCT GND CTLR BECAME INVOLVED IN A HEATED DISCUSSION AFTER THE CAPT DID NOT CLR THE RWY HIGH SPD TURNOFF AS FAST AS THE CTLR THOUGHT HE SHOULD AT IAD.

Narrative

IT JUST TURNED NIGHTFALL AND A NORMAL LNDG WAS MADE ON IAD'S RWY 19R. I WAS THE PF AND AS WE TURNED OFF ON THE HIGH SPD TXWY Y7; I WANTED TO SLOW THE SPD OF THE ACFT DOWN WHEN I WAS SURE THE ACFT WAS CLR OF THE RWY. I WANTED TO GLANCE AT THE MAP ON MY CLIPBOARD TO VERIFY MY POS ON THE ARPT. BEING THAT IT WAS NIGHT; I FELT IT WAS IMPORTANT TO BE AT A REASONABLE SPD BEFORE DOING THIS. ALSO; I WASN'T SURE IF THE HOLD CLRNC LINES WERE IN FRONT OF ME OR BEHIND ME. I KNEW I WAS CLR OF THE RWY; BUT THE HOLD LINES AS I REMEMBER WERE NOT CLRLY LIT AND AS IT TURNED OUT; THEY WERE FURTHER DOWN THE HIGH SPD TXWY THAN I REALIZED. AT THAT POINT; THE CTLR IMPLORED US TO MOVE AHEAD FASTER AND ADMONISHED US FOR NOT EXITING MORE QUICKLY. I WOULD RATHER THE CTLR WOULD'VE HAD ME TELEPHONE HIM AFTER I PARKED AND WE COULD'VE DISCUSSED HIS AND MY CONCERNS MORE CALMLY. THEN; WE TAXIED BACK TO OUR GATE VIA N ON TXWY Y AND R TURN ON TXWY A; TXWY A4 TO OUR GATE. I'M INCLUDING THIS IN MY RPT BECAUSE I CAN'T BE 100% SURE THAT WAS THE EXACT CLRNC AS A RESULT OF THE AFOREMENTIONED DIATRIBE/TAXI INSTRUCTIONS. I ASSUME IT WAS SINCE SUBSEQUENTLY; WE WEREN'T TOLD OTHERWISE. ALSO; I ASKED IF WE WERE 'OK' AT TXWY Y AND INTXN A. THERE WERE NO INCURSIONS; CLOSE CALLS; OR OTHERWISE ABNORMAL INCIDENTS AS A RESULT OF WHAT HAPPENED. I WOULD REALLY LIKE TO SEE THE RWY HOLD LINES BETTER ILLUMINATED ON THIS HIGH SPD TURNOFF.
