Clearly an ATCO response and just as clearly another reason why you need to sit in a cockpit or a centre in London or Frankfurt and listen to how it should be done. Dubai is NOT busy; it is a piece of old doddle. And as for wake turbulence; give me a break... look at the wake turbulence criteria and STOP clearing us to go without the required separation. Too bloody right pal... I will sit there on the runway if cleared to line up without calling ready and sit there until I have the required separation as its me not YOU who will carry the can if it goes pear shaped. Wally!
