The problem is not so much one of being unprofessional or failing to do their job, it's an attitude. Some (and yes it is only some) crew seem to actively hate having to come in to work, complain about having to do any more that 1 sector a day, never do anything downroute apart from order overpriced cr@p on room service and are at best barely civil - at worst downright bl00dy rude.
Just out of interest, spin_doctor, what percentage of crew "have an attitude"; how many times have you flown with those crew members; have they been the same every time you've met them; what about the converse percentage?

And this is a problem because.......
The reason MF has been getting so much praise is not that they are better at their job than others, just that they are much less variable in their interactions.
and you can tell this after how many flights with MF crews?
So far, at least, they are all enthusiastic and pleasant.
and after 3 weeks would you expect any difference.....come back after 15 years and if they are still the same then you can make that point.
