It's obvious some pilots want one rule and ATC are applying their rules / procedures.
As previously quoted, it's ok for pilots to ask for extra time, no problem, but as happened to me very recently
don't bl**dy tell me you want 2 minutes after you have lined up and especially when you know that I'm trying to depart 2 in a very tight gap on visual splits 
Sooooo glad we don't have miked up VCRs
Must say this disease has spread recently at my unit as the associated personnel within a certain blue and white low cost carrier have rotated through.
It's just the lack of consistancy that's difficult to grasp. In my example why did the FK100 ahead in the queue take only one minute separation behind his departing B757 and yet the B738 not?
With this being a repeated thread (every year or so) when is action going to be taken by the standards/authorities?
