Well no, my friend; all the Approach Controller has to do is to ask the Tower Controller either by shouting across the room or by making a quick phone call (I presume that ATC have "Red" phones or even a Squawk Box") as to whether the aircraft on finals has clearance to land. This is not rocket science.
You are saying that it is OK to hand the aircraft over to a Tower controller who is barely in charge of bedlam and is certainly not looking after me who is stupidly trying to land while he is being besieged by the tugs and the dead rabbit collectors which are doing their essential duties.
Now either an airport is for landing on or it is for trying to separate competing ground movements. Which is it to be?
