Narrative:

Before taxiing at destin, I contacted eglin clearance delivery and obtained my IFR clearance, and copied back to controller, and controller stated 'readback correct.' I did not hear, nor did I read back to controller, instructions to contact eglin departure for takeoff clearance. When traffic in the pattern cleared, allowing for a safe departure, I departed runway 14. At a few hundred ft AGL, I contacted eglin departure, stating I was IFR to destination and squawking XXXX (as obtained from clearance delivery). He immediately became irate, chastising me for departing (it was very VMC) without clearance. I apologized to him. He continued to be gruff in his attitude. I followed his instructions explicitly until he turned me over to pensacola approach. Of note is that after I gave my readback to clearance delivery, it took an unusual amount of time for clearance to respond to me. In fact, clearance stated 'sorry for the delay, readback correct.' my guess is that clearance was distraction, and either did not give me the instructions to call eglin departure or did not catch the fact that I did not read back those instructions, or both. If eglin departure was correct when he stated 'it is always this way,' then it should be represented on the approach plates for destin.

Original NASA ASRS Text

Title: IFR MO20 PLT DEPARTS FROM DTW WITHOUT ATC RELEASE.

Narrative: BEFORE TAXIING AT DESTIN, I CONTACTED EGLIN CLRNC DELIVERY AND OBTAINED MY IFR CLRNC, AND COPIED BACK TO CTLR, AND CTLR STATED 'READBACK CORRECT.' I DID NOT HEAR, NOR DID I READ BACK TO CTLR, INSTRUCTIONS TO CONTACT EGLIN DEP FOR TKOF CLRNC. WHEN TFC IN THE PATTERN CLRED, ALLOWING FOR A SAFE DEP, I DEPARTED RWY 14. AT A FEW HUNDRED FT AGL, I CONTACTED EGLIN DEP, STATING I WAS IFR TO DEST AND SQUAWKING XXXX (AS OBTAINED FROM CLRNC DELIVERY). HE IMMEDIATELY BECAME IRATE, CHASTISING ME FOR DEPARTING (IT WAS VERY VMC) WITHOUT CLRNC. I APOLOGIZED TO HIM. HE CONTINUED TO BE GRUFF IN HIS ATTITUDE. I FOLLOWED HIS INSTRUCTIONS EXPLICITLY UNTIL HE TURNED ME OVER TO PENSACOLA APCH. OF NOTE IS THAT AFTER I GAVE MY READBACK TO CLRNC DELIVERY, IT TOOK AN UNUSUAL AMOUNT OF TIME FOR CLRNC TO RESPOND TO ME. IN FACT, CLRNC STATED 'SORRY FOR THE DELAY, READBACK CORRECT.' MY GUESS IS THAT CLRNC WAS DISTR, AND EITHER DID NOT GIVE ME THE INSTRUCTIONS TO CALL EGLIN DEP OR DID NOT CATCH THE FACT THAT I DID NOT READ BACK THOSE INSTRUCTIONS, OR BOTH. IF EGLIN DEP WAS CORRECT WHEN HE STATED 'IT IS ALWAYS THIS WAY,' THEN IT SHOULD BE REPRESENTED ON THE APCH PLATES FOR DESTIN.
