Qu. Why...(and this is the 2nd such occurrence within a couple of months) should I now risk my licence,because have no doubt,if this had gone seriously wrong that is a very legitimate concern...Why should I continue (as I have done for a fairly lengthy career) to allow VFR access if one side cannot follow very straightforward instructions and honour the mutual contract?
I realise this is a different scenario from the one originally posted but I would welcome some rational responses.
The obvious answer is to take up the issue with the individual concerned, obviously after landing and try not to tar every other pilot with the same brush.
