I once tried (in vain) to explain to a UK reg Piper that using QFE was not much help when he asked for it prior to departure at my airfield last summer.
With AD elevation of 250 odd feet and terrain peaks at 5000 feet 5 miles from the field kinda makes QNH the sensible option.
I have seen a good reason to use QFE, ever. Not as a controller or pilot
