I had it from a different perspective yesterday. Was waiting behind a DA40 in NCL who was cleared to enter and backtrack, he then told tower "The aircraft behind me is using much more fuel so I can do a long backtrack if he wants to follow us and go first". It was so nice to hear something like that and I was very thankful.
Where is "NCL"?
Northeast of you 
[?nju??k??sl??p?n?ta?n]
The eastern end of Hadrian's wall!
Yep of course, EGNT in ICAO speak!
But, don't you save a "ton" of fuel by flying straight in or downwind / left base, over say a 6 mile ILS intercept?
Yes, but there's no difference in track miles once they've asked us to call visual - it's purely procedural and we're normally established on the localiser at 12-15 miles anyway.
