I seem to remember being cleared to land on a downwind call at Orlando executive, only to have a turbo prop pilot ask three times for the position of the one ahead, when he was also cleared to land. He being ahead of us on long final. Got to admit this can confuse us Brits who have it drummed into us to get clearance to land on final.
Also i think Icao use to suggest call final on the turn or was this a RAF requirement re the tighter circuit.
