B757 FLC USES IMPROPER PROCS DURING THE DEICING OF THE ACFT AT DAY.

Narrative

SHORTLY BEFORE XA30 LCL AT DAY; WE TAXIED TO THE DEICING PAD #2 FOR DEICING ONLY. THERE WAS NO PRECIPITATION AT THE TIME; ONLY A SNOW CONTAMINATED AIRPLANE. IT WAS AGREED UPON BEFORE PUSHBACK THAT THE GND CREW (2 TRUCKS) WOULD JUST DEICE US USING TYPE I FLUID AT 50%. WITH A TKOF SLOT TIME OF XA53 LCL; WE THOUGHT 2 TRUCKS COULD DEICE US RATHER QUICKLY. AT XA50; 20 MINS INTO THE PROC; THE GND CREW CALLED TO SAY THEY WERE JUST FINISHING UP ON THE TAIL SECTION. THEN GND CTL CALLED; ASKING ABOUT OUR ESTIMATED TKOF. NOW WE ARE THINKING ABOUT EXPEDITING THIS SEEMINGLY SLOW DEICING GND CREW; SO I CALL ON THE LCL FREQ AND ASK IF THEY CAN HURRY IT UP SO AS TO AVOID A LENGTHY GND STOP TO ATLANTA. WE WERE CURRENTLY DELAYED 3 HRS ALREADY. SOON AFTER THAT CALL; THE GND CREW READ BACK AN INCOMPLETE POST DEICING RPT; OMITTING THE 'CLR OF ICE/CONTAMINANTS.' I LET THAT SLIDE; AND ASKED IF WE COULD START OUR ENGS. THEY RESPONDED WITH 'START ONLY THE L ENG; WE SPOTTED A PATCH OF SNOW ON THE R ELEVATOR; WITHIN A FEW MINS; WE WERE CLRED TO START R ENG; FOLLOWED BY A 'YOU ARE CLR' WHEN ASKED IF WE WERE CLRED TO TAXI. WE THEN SWITCHED TO GND CTL FOR TAXI. UPON ARR AT ATLANTA; WE WERE TOLD THAT THE DEICING CREW WAS NOT FINISHED; AND THAT THEY DENIED CLRING US TO START ENGS OR TAXI. IF I HAD REQUESTED A FULL AND PROPER POST DEICING RPT TO BEGIN WITH; ALL DOUBT WOULD BE REMOVED.
