I'm not one of those people who say "it never happened to me so it must never happen" folks but all the runs I've done people have been extremely courteous to people wanting to watch cutscenes. In fact, the only time I ever missed a battle because I was watching a cutscene was when someone got knocked back into the arena by a monster thingy.

I think the commendation system has done a lot to encourage people to be pleasant and I'd like them to go more in that direction. Better rewards, ability to give out more commendations, etc.
