I think QF is just finding it too expensive to run the F lounge with the same amenities that it opened with. The wine is a bit cheaper, the amenity items are not in the showers anymore (personally I think QF meant for them to be used in the lounge, not taken for future use), etc. Been in the F lounge 1-2 times a month for three years now, and the level of amenity has degraded somewhat over that time.
People stealing spoons is just, well, what do I say? Personally I know some people who've purloined QC cups, plates, glasses etc. Somewhere QF needs to be making enough profit out of people flying to pay for all of this, and there isn't much profit in Y fares, or JQ 35/36. And maybe not enough people flying in J/F.
