CAPT OF AN ATX JET CHARTER FAILED TO MAKE ALT XING FIX.

Narrative

ORLANDO APCH CTL INSTRUCTED US TO CROSS THE LEESE INTXN AT 11000 FT MSL. I TIMED OUR DSCNT JUST RIGHT IN ORDER TO COMPLY WITH THE XING RESTR. THE WX WAS IMC AND THERE WAS OCCASIONAL LIGHT TURB IN THE AREA. DURING THE DSCNT OUT OF 13000 FT; OUR EXECUTIVE PAX INSISTED ON BEING SERVED SOME WATER. SO RELUCTANTLY; I ASKED MY COPLT TO OFFER SOME ASSISTANCE. WE WERE STILL APPROX 20 NM OUTSIDE OF LEESE INTXN AND I HAD NO RESERVATION THAT WE WEREN'T GOING TO MEET THE XING RESTR. WHEN MY COPLT DIDN'T RETURN AS QUICKLY AS I HAD ANTICIPATED; I BECAME DISTR AND ORDERED HIM TO RETURN TO HIS POST SINCE THE TURB WAS GETTING MORE MODERATE. IT WAS DURING THAT MOMENT THAT I NOTICED WE WERE ALMOST OVER LEESE INTXN AND WE STILL HAD ABOUT ANOTHER 1000 FT TO LOSE. I IMMEDIATELY BEGAN TO INCREASE OUR RATE OF DSCNT AND OUR GPS SHOWED US XING LEESE INTXN BTWN 12000 FT AND 11000 FT MSL. I EXPECTED TO HEAR SOMETHING FROM THE APCH CTLR; BUT HE WAS EXTREMELY BUSY DUE TO THE POOR WX CONDITIONS AND WE WERE HANDED OFF TO THE NEXT CTLR. THE REST OF THE FLT WAS UNEVENTFUL. ALTHOUGH CUSTOMER SVC IS VERY HIGH ON MY LIST OF DUTIES; THAT WAS NOT THE RIGHT TIME TO ALLOW MY COPLT TO LEAVE HIS POST TO CATER TO OUR PAX'S NEEDS. LOOKING BACK; I SHOULD'VE WAITED UNTIL AFTER THE XING OF THE FIX BEFORE ALLOWING MY COPLT TO LEAVE HIS POST. MY COPLT COULD'VE ALSO EXPLAINED TO OUR PAX THAT IT WASN'T A GOOD TIME TO BE LEAVING HIS POST AND SHOULD'VE JUST SHOWN OUR PAX WHERE THE WATER WAS LOCATED. THERE IS NO ROOM FOR DISTR IN THE AIR.
