Take on board all of the above opinions, I fall generally on the side of good discipline. However, IMHO a much bigger problem is the apparent need of many pilots to speak insanely quickly and (some) so heavily accented that it is impossible to understand a single word that they have said.
They are speaking plenty but communicating nothing. For heavens sake slow down, it's not a race.
Regarding the accented comment above, please don't consider this a racist jibe as I come preprogrammed with an accent. I do however make a point of neutralising it at work.
