On recent flights between SYD and MEL I have noticed on 2 occassions, people in row 3 putting their feet on the bulkhead dividing J and Y cabins. On the flight to MEL my neighbour in 3C decided to slip off his shoes (left socks on) and put both feet on there. On the flight back to SYD my neighbour in 3A slipped off his shoes and put both bare feet on there. They weren't just above the magazine holder but literally at head height on full display for everyone. Who the hell are these people? And do they do this everytime they fly?? I would expect better manners from my 4yr old nephew.
