This flight was weird as I couldn’t event tell who the purser was....the person taking jackets was different from the one who offered the lackluster PDB and took meal orders.....if it was the one taking meal orders, this FA kept hiding in the galley with no tray clean up or proactive drink refills while the one who floated between FC and coach did most of the work.....they were both very young but one clearly took more pride in their job (floater) than the other (sloppily dressed guy who stayed in FC).
