A B767 flight crew reports that there was, apparently, miscoord between TRACON and ARTCC over altitude assignments. The approach controller questioned the flight crew as to why they were at 14000 ft versus 12000 ft which is the usual altitude.

Narrative:
Inbound to atl on the sinca 3 arrival. We had numerous step down altitudes because of the spacing on the aircraft ahead. Normally we would cross canuk at 250 KTS 12000 ft. However, the last clearance was to 14000 ft and then we were passed onto the next controller. When we reported 14000 ft, he questioned our altitude clearance. Summation: approach controllers are under too much pressure for minimum spacing, maximum arrs per hour at major airports!!

HOWEVER, THE LAST CLRNC WAS TO 14000 FT AND THEN WE WERE PASSED ONTO THE NEXT CTLR. WHEN WE RPTED 14000 FT, HE QUESTIONED OUR ALT CLRNC. SUMMATION: APCH CTLRS ARE UNDER TOO MUCH PRESSURE FOR MINIMUM SPACING, MAX ARRS PER HR AT MAJOR ARPTS!!
