Heck, I'm in NYC where we are notoriously rude and the folks keep coming and my taxes are sky high!!!
Serously, though, I see what Matt is saying. It's like the "ugly American" thing - please, come, enjoy, but don't get mad at us if it isn't how you expected.
Here's my tip:
I understand that you are in NYC and it's huge and hard to navigate if you are not a regular. So, if you need to check your map, or stop and think about something, PLEASE move to the inside of the sidewalk, like, right next to a building. Do not stand in the middle of the sidewalk or at a corner where people are trying to cross the street. I know you are coming as a tourist, but remember that this is my home and I have to do all the errands on my lunch hour that you do on yours back in your town. How would you like it if I came and stopped up the traffic on your streets?
