A common one I'm sure.
Busy Flustered Me: AirIndia123 Request your descent point.
AIC123: Ahhhhhh Say again...
Impatient Annoyed Me: I Say again!! Request your Descent Point...the Point you wish to begin your descent (in a very condascending tone)
AIC123: Well if you insist 100 NM to run Bombay.
Why funny you ask.... well I was doing arrivals into Dubai (UAE)...oops.. bloody overflyers they never fit in the sequence.
