There was nothing malicious in the drinks making (and certainly no cost saving drive), simply a confusion of standards between Club World and Club Europe. Longhual Club you shouldn't see any cans/miniatures in the cabin anymore.
I certainly wouldn't be getting unnecessarily upset by this. It probably won't happen again (until new standards, whatever they may be, do come in), but in the meantime if the drinks are being made in the galley (rather than served straight off the trolley), then simply ask to mix it yourself.
