Hey Sky,
I think that generally, although the crew may not just tell a pax that they don't want them to be there, they have a fantastic ability to make it incredibly obvious that they don't want the company. But in all honsety, in my experience this rarely happens and most of the time the crew will have the time for the pax.
Yeah, finding the transition absolutely incredible, even though very hard work, and looking forward to getting back up there as an f/o.
