Walking down Kirkwood on a weekend night and all you see is a bunch of loud ass kids, getting drunk or whatever. I agree with you, the foreigners here are more polite and respectful.I must be the oddball, because in my experience 99% of foreigners I've interacted with in this country have been more polite and respectful than my average countrymen.
Maybe it's because I don't frequent touristy spots very much, so I'm meeting people who came to the country to work or study, not to vacation...
