Perhaps the lounge offering has been intentionally downgraded so that people don’t have great expectations of the F cabin which is also sub-par.
As to the promotion of the food event, the handles promoting it seem to have a few things in common, they promote BA at every turn and display ignorance of alternatives. They are also prone to being abusive to posters who disagree with them and often out of touch with reality of business travel and the wider world in general.
It’s quite difficult to believe that such similar posts come from different people. In future I think I’ll refer to the KrugHandles when I need to refer to them. It might catch on!
