MLG FLC RECEIVES POOR TREATMENT AFTER CORRECTING CALL SIGN AND PROPERLY REQUESTING CAT II APCH AS DEN CTLRS GO FROM UNPROFESSIONAL TO DANGEROUS.

Narrative

ACR #1 XXX; SEP/XA/99. WHILE BEING VECTORED TO INTERCEPT ILS RWY 35L; ATC MADE 2 CALLS FOR ACR #2 XXY. WE DISREGARDED THE CALLS. ATC CORRECTED MISTAKE; CLARIFIED ACR #1 XXX AND APOLOGIZED. WE HAD ALREADY NOTIFIED APCH OF OUR INTENTION TO EXECUTE 'AUTOLAND' INTO DEN. A DIFFERENT (AGGRESSIVE) CTLR TOOK OVER AND DIRECTED US TO MAKE 90 DEG TURN TO INTERCEPT LOC WITHIN 1/2 MI. WE HESITATED ON OUR REPLY; DUE TO OUR NEED FOR A 30-40 DEG INTERCEPT IN ORDER TO EXECUTE AUTOLAND. ARGUMENTATIVE CTLR CANCELED VECTOR; ISSUED 270 DEG HDG AND INFORMED US THAT WE HAD MISSED OUR INTERCEPT AND WERE NOW 'NUMBER LAST' FOR APCH. AFTER NUMEROUS VECTORS; AND OUR REMINDER THAT WE REQUIRE A PROPER INTERCEPT AND HIS REPLY 'OH; YOU'LL GET IT' SARCASTICALLY; WE INTERCEPTED THE LOC. THE INITIAL CTLR RETURNED; CLRED US FOR ILS RWY 35L AND ADVISED US TO CONTACT TWR. OUR READBACK WAS 'CLRED FOR ILS RWY 35L CONTACT TWR AT DYMON.' ARGUMENTATIVE CTLR RETURNED AND STATED THAT WE WERE 'WRONG AGAIN; CONTACT TWR NOW AND CALL TRACON UPON LNDG.' THE CAPT ASKED FOR HIS NAME AND HIS REPLY WAS; 'I DON'T HAVE TIME FOR YOUR QUESTIONS!'
