It's more annoying when pilots first call: "Request" and then pause...rather than to state their request on the initial call-up....Why? Because the controller may actually hear you the FIRST time. Get it?
It's also annoying when during multiple verbal exchanges in the same brief conversation, pilots keep repeating their full call sign, over and over, like a parrot. Needless to say, there is such a thing as VOICE RECOGNITION...because you had just talked to the controller seconds earlier, no? ...Would someone else be masquerading with your identical voice?
