The discussion about the best chief stew:
If we're just talking about the TV version of it, Hannah has more charisma and attitude (don't mind being there for the drama) than Francesca. But when it comes to doing a job, Hannah was always to keen on cutting corners and not really having that high standard that she told everyone about.
Francesca seems to be really into doing a good job for the charter guests. On the occasions when the interior team didn't deliver I feel that her reaction also has something of "I failed the guests" in it, which to some extent is a good trait if you work in the service industry. Hannah would just shrug her shoulders and care less about what the guest experience.
I also miss Kate, but I like the fact that she moved on after many years in yachting.
