Thansk for information everyone..
We have also published in AIP as "unless otherwise notified by ground control, pushback shall be done to the direction of the runway" so i said to pilot i don't have to say face to... but he insisted to say, face to which
So now you have a proof that the notification in AIP simply doesn't work as you expect. A pilot - when in doubt - will ask you and it's your job to provide assistance. IMHO saying "face XXX" instead of "rwy 06" takes the same time but is significantly more helpful to the crew.
