Captain Sand Dune, you're right, what a wank, especially that ATC lot who seem to have to say it all the time...I mean everyone should automatically know better.
I'm with the other camp, I think it's not a bad idea, definitely not a "Wank" or "Big Noting" probably a few guys who have seen a couple of lighties line up behind them not thinking about the ramifications of what they're doing, but only if there is actually someone else behind you about to line up and/or land otherwise why bother?
