Criss - I appreciate your direct answer, however, my point is somewhat being missed I fear.
When I go swimming with my kids at the weekend - I pay my £5 entry fee just like the man at the front of the queue, but I don't push in front of him because I've paid for the same use of the water/slides etc. So I'm not quite sure where you get the idea that paying the same for something gives you the right to push in?
However, I digress. My main point is, surely in order to reduce RT congestion in passing speed/hdg etc and in order to co-ordinate traffic more optimally, then why not start the ball rolling correctly on the ground?
I'm sure there are plenty of pilots who like nothing better to call ready to push the moment someone else has just received a clearance (with a cheery 2 fingered salute) - I am just surprised ATC allow it to happen - particularly as it screws their mates up further down the line!
S.D.
