In BOS-NYP Acela F on 9/11, the F attendants weren't using the tables. One attendant had her stuff on the left-side seat pair closest to the galley, and the other had his stuff on the right-side single seat's traytable two rows back from the galley (the seat right in front of me). When someone boarded midway along the route and asked the female attendant if anyone was sitting in the seat in front of me (I think it was the only single seat left that was aligned with a window), she said it was her partner's stuff but he wouldn't mind being moved, so she moved his stuff to another seat.

Good service and classy behavior, although I'm used to west coast Alaska Airlines flight attendants who smile more (people on the east coast seem to be more efficient but smile less). No complaints.
