I've read all of these posts above and, as regulars here probably know too well by now, am often the first to complain about everything.
In the 40 years of paxing since BA came along (and indeed back to their predecessors) I have NEVER, not once, encountered rudeness from any BA staff*. Either I have the most amazing luck, or they actually are a cut above the rest, somehow not reflected here for some reason.
Well done all. See you soon
