It matters because you, the stickler for grammatical accuracy, asked a
general question (which was triggered by a specific context).


You're contradicting yourself. It would have been a general question
without the quoted material, but the quoted material was there.



That depends on the reason the takeoff clearance was immediate, and (if
it's due to incoming traffic) how close it was. Cancelling the takeoff
clearance and telling the landing traffic to go around (if that's what the
issue is) comes to mind.


It was due to incoming traffic and the traffic was close enough to require
an immediate takeoff or wait for the traffic to land.



You're a controller. What would your response be?


"Unable. Cleared for immediate takeoff or exit the runway without delay."
