In the West, we can choose whether to stand on the escalator, run up the down escalator (something I've always wanted to do) etc. As long as people don't block the escalator then I think it's fair enough, people can do what they like and it's not up to us to tell them to do anything other than that. We are already told to do so much in life, why can't we stand and think about how we are going to get from the airport to our hotel, etc. on the escaltor. The thing that annoys me are kids who'se parents let them sit on the baggage carousel and run around the arrivals area so you can't get to the front of the crowd to get your bag, without knocking over/walking on the kid however tempting that might be...I don't do.
