Not trying to be controversal... hmm actually I am. Considering the people that can actually enter the F lounge, basically all the HONs, everyone managed to grab a good miles deal and a few really paid for F... Saving on the champagne is actually quite an easy one. I'd say, a lot of pax have no clue about champage (me neither, I know Krug is considered good). Some staff at the SEN whisky bar told me once, people are just requesting the most expensive whisky. Not because it's the best, because it's the most expensive. A majority will not be able to differentiate based on taste/smell/quality--neither whisky not any other booze. Based on that, it's an easy (and maybe necessary gain) if you are keeping the selection on a reasonable level.
