Ha ha lhr pony has demonstrated that he frequently gets the wrong end of the stick and is an eejit.
I don't think you have. As Gonzo says there is misunderstanding as to what the procedure means and who has responsibility. I occasionally get a readback of cleared to land when using land after with non-UK crews, they have clearly mis-understood the instruction but on short final is not perhaps appropriate timing to discuss this. And by the time you had corrected them the conditions probably exisit for a landing clearance, although it would perhaps be too late at this point to do much other than land.
I don't think that crews are "at fault" for not knowing what the procedure means, nor do I get annoyed when an aircrew correctly go-around following a land-after if they are not comfortable with the separation that they are now responsible for.
