One of my biggest pet peeves that sets me off a little every time is when I saw "what" and they say it again at the same volume and speed.

Then I glare at them for two seconds, and loudly and slowly say "WWWHHHAAAAAATTT?" and they act affronted for having to repeat themselves again.

I had a clearance delivery controller do this to me:

"Cessna 123AB, cleared to Somewhereton Regional as filed, Runway 5 MUNCH departure, climb and maintain 5,000 feet, expect 9,000 feet in 10 minutes, contact Exampleville departure 122.9, squawk hubbajubba."

"Exampleville clearance, Cessna 3AB, could you repeat the squawk code?"

"Cessna 123AB, cleared to Somewhereton Regional as filed, Runway 5 MUNCH departure, climb and maintain 5,000 feet, expect 9,000 feet in 10 minutes, contact Exampleville departure 122.9, squawk hubbajubba."

"Exampleville clearance, 3AB, I still didn't catch the squawk code. REPEAT THE SQUAWK CODE."

"Cessna 123AB, cleared to Somewhereton Regional as filed, Runway 5 MUNCH departure, climb and maintain 5,000 feet, expect 9,000 feet in 10 minutes, contact Exampleville departure 122.9, squawk hubbajubba."

"Exampleville clearance, 3AB, cleared to somewhereton as filed, MUCH departure, maintain 5,000 feet expect 9,000 in one zero minutes, call departure on 122.9, squawk 4422?"

"3AB, readback correct, call ground point niner."

I get this a lot with other languages, but especially Spanish. I sound like I'm fluent, but I can't understand it when spoken back to me for shit
