Narrative:

Atx X was cleared from jvl to ptk airport, radar vector teddy, direct ptk. I queried the controller if this was teddy or petty intersection. I even read the intersection spelling phonetically. The controller further stated (irritably) that I need to go to petty. After my handoff to rockford approach, they queried me, 'where are you going?' when I told them petty intersection, they thought I was nuts. Immediately instructed me to go to teddy intersection. I did, and queried them on why a controller gave me the wrong intersection.
