In regards to boorish behavior, we are currently on the Viking Neptune and have been amazed ~ appalled? ~ by the number of times we have seen bare feet on seats, pillows, cushions, etc, not to mention lots of feet ~ in shoes thankfully ~ being rested on the chairs/cushions in front of them in the theatre. As much as I would like to have my feet up, I would never think of putting them on the backs of other person’s seats!
