Slasher,
In my 30 plus years of having come into singapore on a wide body i have NEVER BEEN 'number 15' in departure sequence. And even when i have been close to those numbers, i have never been delayed by more than 3-4 mins max!
I have only the best of comments and reservations when it comes to ATC singapore. A thoroughly professional lot.
Not removing anything from the fella who wanted to wipe his landing gear clean on the grassy patch of the golfing greens though ...
