Narrative:

I came out of mdw, VFR to the southwest. Was cut loose by chicago approach. Had been flying 2000 ft per clearance. I requested an attempted handoff, got it, and was asked what my heading and altitude would be, 238 degrees and 4500 ft. Instructed to climb to 4500 ft, but not cleared into class B, where the edge was 3600 ft. Climbed from 2000 ft to 3000 ft and held it there for 10 mi, about 3 mins (15-25 NM DME from ord). Had lots of traffic to look out for, he was busy. Did not get to ask if cleared into class B. Just as I was exiting the 25 NM veil, the controller says, 'hey, are you going to get around to climbing to 4500 ft as I instructed?' I replied, 'yes, sir, but you did not clear me into class B and I was not about to clip the corner.' no magic 'cleared into class B.' 3 mins had elapsed. He replied, 'well, I have some magic words for you, squawk VFR good day!' my private student who was along for the ride is now even more afraid to talk on the radio. Called up chicago approach. They corrected the controller for non standard phraseology. They pointed out that no VFR pilot is going to climb into class B unless cleared.

CLBED FROM 2000 FT TO 3000 FT AND HELD IT THERE FOR 10 MI, ABOUT 3 MINS (15-25 NM DME FROM ORD). HAD LOTS OF TFC TO LOOK OUT FOR, HE WAS BUSY. DID NOT GET TO ASK IF CLRED INTO CLASS B. JUST AS I WAS EXITING THE 25 NM VEIL, THE CTLR SAYS, 'HEY, ARE YOU GOING TO GET AROUND TO CLBING TO 4500 FT AS I INSTRUCTED?' I REPLIED, 'YES, SIR, BUT YOU DID NOT CLR ME INTO CLASS B AND I WAS NOT ABOUT TO CLIP THE CORNER.' NO MAGIC 'CLRED INTO CLASS B.' 3 MINS HAD ELAPSED. HE REPLIED, 'WELL, I HAVE SOME MAGIC WORDS FOR YOU, SQUAWK VFR GOOD DAY!' MY PVT STUDENT WHO WAS ALONG FOR THE RIDE IS NOW EVEN MORE AFRAID TO TALK ON THE RADIO. CALLED UP CHICAGO APCH.
