I've never even gotten yelled at. Quite the opposite. Once were were doing practice approaches at KFTG (under/near/virtually on top of) the DEN Class B. Our radioed missed approach instructions would bring us up into the B airspace*. My "Confirm cleared into the Bravo" received the friendly reply, "Oh yeah. You need that don't you. Cleared into the Class Bravo."

* It didn't have to. If we did a normal climb to altitude we would enter the B. But we could have leveled off, remained below the B, and then about 1 mile or so later, continued the climb.

For those who believe that heading and altitude = clearance, willing to act on that that implication a mile or so from the Class B surface area?
