C180 PLT TAXIED WITHOUT APPROPRIATE GND CTLR CLRNC.

Narrative

ENTERED THE L DOWNWIND FOR RWY 17L AND LANDED. I WAS ADVISED BY THE TWR TO CONTACT GND CTL 121.80; WHICH I DID AFTER EXITING VIA TXWY A5. I WAS THEN TOLD TO PROCEED TO THE RAMP FOR TAXI TO AREA 'GULF.' HOWEVER; THE RAMP WAS FULL WHAT WITH GND VEHICLES VYING FOR THE FUELING OF A LARGE JET THAT WAS BLOCKING THE RAMP FOR MY GOING S ON THE RAMP. THE GND VEHICLES WERE ALSO BLOCKING THE RAMP ENTRY. I DID NOT WANT TO CREATE AN ACCIDENT BTWN MYSELF AND THE GND VEHICLES; AND THE JET; WHICH WERE BLOCKING THE RAMP AT THE TIME. SO I TOOK THE TXWY S AND THERE WERE NO ACFT TAXIING IN EITHER DIRECTION N OR S. I WAS THEN CHEWED OUT BY 'GND CTL' FOR HAVING DONE SO; AND AS I EXPLAINED TO THE CTLR THE AREA WAS TOTALLY BLOCKED AT THE TIME; AND WAS FURTHER CRITICIZED FOR TAKING THE TXWY (EVEN THOUGH NO ACFT WERE ON THE TXWY). I TOOK THE ACTION; IN MY ESTIMATION; BECAUSE OF SAFETY FOR MYSELF AND MY ACFT. AND WHEN IT COMES TO THIS KIND OF JUDGEMENT; IT'S THE PLT'S CALL. I WAS FURTHER TOLD TO GET OFF THE TXWY AND I MERELY SAID 'YES SIR.' I DID SAY IT IN A GRUFF MANNER; BECAUSE I THOUGHT THE 'CTLR' WAS EITHER UNKNOWING OF THE SIT; OR DIDN'T CARE; AND I WAS TOLD TO DO 'WHAT I TELL YOU ATTITUDE' REGARDLESS OF CREATING AN INCIDENT; AND THIS WAS AND IS A 'PLT'S' DECISION. MY ERROR MAY HAVE BEEN NOT TO IMMEDIATELY TELL THE CTLR THAT I WAS TAKING THE TXWY WHICH WAS FREE OF ANY ACTIVITY WHATSOEVER; AND WAS OUT OF HARM'S WAY. I PROCEEDED AND TAXIED TO MY TIE- DOWN IN AREA 'GULF' WITHOUT FURTHER INCIDENT. IT APPEARS TO BE THIS MAY HAVE BEEN A NOVICE CTLR; WHO EITHER DID NOT KNOW OR DID NOT CARE ABOUT THE CIRCUMSTANCES; AND WHO WANTED TO EXERCISE HIS AUTH -- THIS APPLIES SOLELY TO THE 'GND CTLR.'
