NYC Most Polite

A recent "study" in National Geographic puts New York City at the top of most polite cities in the world. I guess we beat out the traditional polite cities of Zurich and Toronto (take that, Canada!). According to the article I read, they set up certain situations and recorded how random people dealt with them. New York received a total score of 80, where Zurich got a 77 and Toronto a 70.

The Top 10 Polite Cities are listed here:
1. New York City, USA
2. Zurich, Switzerland
3. Toronto, Canada
4. Berlin, Germany
5. Sao Paolo, Brazil
6. Zagreb, Germany
7. Auckland, New Zealand
8. Warsaw, Poland
9. Mexico City, Mexico
10. Stockholm, Sweden

The city at the bottom of the list was Mumbai, India (scored a 32).
The only problem I see with this "study" is that all of the data in NYC was collected at various Starbucks locations throughout the city. I feel that there has to be some sort of selection bias going on there. At that point, you're only studying people willing to spend $4.00 on bad coffee.
