Post # 3 - Transportation Etiquette

    There're many transportation etiquette from written things to unwritten things. Don't put on your leg on the seat. Don't smoke. Please give a seat to elderly people. These things are written. But I think unwritten things are very important, because there are each other person's moral. For example, don't speak loudly and don't use the seat more than necessary like these. If we're careful to these things, we can use public transportation very comfortable.
