Which community in the world displays the most graciously considerate manners?

I was thinking about this on the way to work this morning after having the most unfortunate wet seat on a bus experience. I began wondering if this were to have happened in another part of the world, if someone had spilled liquid on a bus seat, would the culprit have cleaned up the mess or at the very least provided a warning for others not to sit on the spot.

I would like to think that most people are considerate of others, but I’ve learned through experience that manners have become the exception and not the rule.

Where in the world does the majority in a community practice graciously considerate manners?
