Yeah, I'd figure it's about the same everywhere in the world. I doubt that there are some great standards in any country (maybe Japan? - they seem to be perfectionist about everything ), but I'm sure some countries are much worse in this regard. I heard that it's common practice in som e African countries to show rolls of film in random succession. Sometimes the last roll is shown at the beginning, sometimes in the middle of the screening, etc. (probably only foreign films, though).
