For some reason, many controllers seem to cover their backs nowadays by saying 'poor radar performance' or something similar. This only refers to low coverage, not to overall accuracy which is regularly (at least in the UK) checked.
I once watched a certain rock star attempt to fly his own approach into Blackbushe in his newly purchased Navajo (normally flys a Harvard - gives the game away doesn't it!) . We could see he was on final for Lasham not Blackbushe, but no amount of us telling him would convince him until he broke cloud and could see we were right.
