I had a guy at St Lou Approach that snapped at me because we weren't on the same page. Other than that most controllers are great.
Had a controller at a class "D" 3 years back who could not comprehend I couldn't ident because I didn't have a transponder, and I didn't have lights I could blink, because I didn't have an electrical system.
Even the concept of a battery powered handheld radio was beyond their capability to understand. After the third "Please ident" and my polite negative response, the Supervisor came on and apologized for the "new kid".
You'll have someone in the LAX VFR corridor (the busiest airspace in the world)
Not the corridor. Infact, the special flight rules area is sometimes downright dead, I think many of the school scared their students away from using it. But the dude who came to one of our club meetings (just before pandemic, when we had quarterly banquets) was from Socal Tracon.. he had a bar graph up of the top 20 busiest airspaces in the world by number of plane movements and the LAX area was at the top, by like a factor of two. New York, Chicago, were up there too.. he had some cool stats up there. Surprising to see how far down the list other "busy" areas were like London, Atlanta, Frankfurt.. but the GA footprint is also much smaller there (for Europe at least)Wait, the corridor is the busiest airspace in the world? I used to fly it quite often going to and from SNA in the Bonanza and don't remember it being all that busy. Granted that was a decade ago though....
