Also, not excusing the crew's responses since they should be trained to deal with difficult people, but it doesn't seme like Ben was really helping himself. To take one example, when he said beets and she said goats cheese, he knew what she meant so why not just say 'yes'?
Never had a mixed drink on BA - is mixing it for the passenger standard?
Few will be surprised to learn I think he was spot on. In my experience CW is an awful product and BA crews are simply poor. I have had crew as he described in F. Overall therefore his experience is much the same as my own.
My A380 flight in F with wife and daughter in J was my last with the family on BA. To say they were amateur would be generous and every aspect of the experience from the boarding to disembarkation was awful. The senior crew member was only interested in her mother who was propped in the crew seat by the door. Since then its been AA going west and either CX or QR going east. The difference is simply astonishing. Its not that AA are blingtastic simply that they have a superb hard product and their crew seem proud to be working in/on it. The food is plain but you get your first choice. QR and CX however are own a different level altogether.
