Starting sentences with "I'm from New York"

I think if you mention that you're from New York more than three times in a short conversation, you are an asshole.

Actually, saying you're from anywhere too much makes you an asshole, but more often than not New York is the place mentioned most.

Examples from tonight:
'I'm from New York, so I'm not used to smoke in bars.'
'I'm from New York, so I think everyone here is being snooty.'
'I'm from New York. New York New York New York.'

Even worse was this lady was from the state, not the city, but by saying 'I'm from New York' she can try to cling to the city's glory even if she lives in the less awesome state.

Anyway, after this lady talked about New York I forced her to eat a hammer.

What do conversations with these people sound like when they're actually in New York? "Well, I'm from here, so... fuck yeah I like mustard." I don't think you need to provide a context when you're discussing mundane shit. None of my mustard conversations have involved geographical backgrounds.
