Lots of flying in NE corridor, (mostly to TEB) Also lots around ATL, HOU, ORD and SOCAL.
Everybody talks fast. Everyone wants something from you that you aren’t conveniently able to provide.
For example, I regularly fly both turbines and geared piston twins. Often, I’ll be held in the flight levels until 25 mi from the threshold by center, and turned over to approach with an an entirely doable approach in a King Air or Citation, but with no hope in heck in a 421. “Unable” works well, and forgoing snide vernacular on frequency, while stating my requirements when asked, usually produces the sterling service that those at busier facilities are winnowed to provide.
