I sometimes think I am the only stuffy person who dislikes seeing feet on bulkhead (so much so that it's one of the reasons why I do not sit at the bulkhead in case I have a seat neighbour who does this), but I'm glad to see that I am not the only one. My husband thinks I'm really stuffy for disliking it.
Having said that, the cabin crew should have asked in a nicer way not to do it.
