I don't think it's a crew shortage - it sounds like a crew who just couldn't cope or weren't trying (or both). There are 3 F crew but if the load is under 7 (I think) then 1 cc may be released at CSD/CSM/CM discretion to work elsewhere, or so I understand it.

This is weird. One thing about MF I've noticed is that they tend to stick rigidly to the service standards and F crew should be trained specifically for the role. I understand slow service if crew are inexperienced but I'm pretty sure they have a manual they can look at if unsure. But things like setting the table with a knife and fork or offering something to drink is just elementary and shouldn't even require training! Fine they may set the table up back to front or might forget little things but basic hospitality skills should at least dictate "what do you want to drink mate?" The premium service training should just refine those skills!

This isn't typical service (for any fleet) on BA.

It's probably worth a brief note to Customer Relations.
