I do a lot of work - in flight safety - with the FAA (Orlando), alongside an air traffic controller from MCO (Orlando Int).
One of his pet gripes is people reading back too much - and during his lectures to the listening public is constantly saying "If I give you a full airways departure and route clearance, all I need to hear back is "Roger" ".
Before you scream at me - I have screamed at him - on numerous occassions - saying that this does not comply with ICAO.
