B737 CREW IS CHASTISED BY A DFW GND CTLR FOR CONTINUING TO TAXI AFTER CLRING THE RWY.

Narrative

OUR FLT LANDED AT DFW UNEVENTFULLY AND WAS CLRED TO EXIT OUR LNDG RWY 36L AND HOLD SHORT OF RWY 36R. WE DID SO; AND LATER WERE CLRED TO CROSS RWY 36R BY DFW TWR CTLR; WHICH WE DID. IN MANY PREVIOUS EXPERIENCES AT THE ARPT; WE HAVE BEEN ENCOURAGED BY CTLRS TO EXPEDITE CLRING THE RWY FIRST; THEN CONTACT GND CTL ONCE CLR. TRADITIONALLY; IN OVER 5 YRS OF FLYING INTO THIS ARPT; MY EXPERIENCE HAS BEEN THAT GND CTLRS WERE VERY RELAXED; AND MOST LIKELY TO JUST LET US PICK THE TAXI RTE WE DESIRED TO OUR GATE. I MENTIONED THIS BECAUSE IT DEFINES A PATTERN THAT CTLRS AT DFW HAD DEVELOPED THROUGH CUSTOM AND REPETITION; SO IT BECAME A TAXI METHOD WE CAME TO EXPECT BECAUSE IT 'HELPED DFW CTLRS OUT.' IN THIS CASE HOWEVER; IT WAS DIFFERENT. WE CLRED RWY 36R; EXPECTED CLRING THE RWY; AND AS WE HAD MANY TIMES IN THE PAST CONTINUED TAXIING SLIGHTLY AS WE ATTEMPTED TO CONTACT GND CTL. WE RECEIVED NO RESPONSE. AT THIS MOMENT WE WERE ON TXWY WK; SLIGHTLY PAST TXWY F; EXPECTING GND TO CLR US TO OUR GATE VIA TXWY G. GND CTL FINALLY RESPONDED ON FREQ; ASKING IF WE SAW AN RJ ON ADJOINING TXWY G. THE GND CTLR SAID THIS RATHER TESTILY. WE RESPONDED THAT YES WE SAW THE RJ; AT WHICH POINT GND CTLR REBUKED US SAYING THAT IN THE FUTURE; WE SHOULD NEVER CONTINUE TAXIING UNTIL CLRED BY GND WITH A SPECIFIC CLRNC.
