Were you on an IFR flight plan?
Don Brown has an excellent set of articles on Avweb about the shortcuts pilots and controllers take that are not inline with the AIM or FARs. He wrote extensively about why navigating to an airport is not how the system is set up, but controllers accomodate it because its easy to put up with it (take that shortcut) than it is to force pilots to operate the way the system was designed.
Yes, I was at FL430 when I got the instruction. I honestly cannot remember the last time I flew on a VFR flight plan
