HI all,
As far as I'm concerned, politeness is a must; with niceties if time allows. Simple as that.
I was taught by someone who pointed out to me that if a pilot said goodbye to me I would almost automatically respond with goodbye, taking an extra transmission, whereas if I said it as I transferred them the extra transmission would go.
Of course if you are so busy that the r/t time is that precious that all niceties should dissappear then they should, but perhaps it also means that you're just a bit too busy and should maybe be split/regulated?
Besides, I'm a friendly type by nature, and I enjoy my job. Why shouldn't I try to make another persons day a little nicer by being pleasant if I can be?
(Or outrageously flirtatious if time allows....

)
Cheers,
N
