Why doesn't Dubai use a C. Delivery??
Everytime I've been there it's been ground doing both, and people stepping all over each other trying to get push and start, taxi, clearances.
It gets pretty frustrating trying to get a word in edgewise, had to wait half an hour from getting start, to getting taxi, while we had to listen to a certain controller berate the poor Iranian "Assman" and he was making the point of saying "Ass" read his clearance back 4 or 5 times.
Totally unprofessional, it almost seemed like he was enjoying bringing things to a grinding halt, until someone else took over the fq and got the traffic moving.
End of Rant
Sorry for spelling
