I think ATC at ABZ are great and often say how lucky we are not to have slot times, it would be a nightmare! Just take a bit more fuel in the mornings and I think oil companies use taxi time and not take off time as an on time departure so no idea what all that fuss is about.
But only really posting to let the ATC guys know which controller is called Miss Whiplash by double bogey and many others, she's the one who always used to say "correct" in a certain way!?
