It's not distance it's behaviour.

You can be from the other side of the planet and as long as your respectful doesn't really matter. But there is certain types of people, typically those who come in large coaches with lots of other people, that can tend to be rather obnoxious and shove their way to the front, so they can take the same picture that everyone takes in front of whatever local monument you wish to substitute.

Often they seem to be Chinese.
