You are going to probably hate it. Not that it's bad. It is really, really polite compared with say, the middle part of the country, nevermind California. The typical interaction in California -- if you did that -- would be like throwing a cup of icewater (no, a whole bucket) onto your typical North Carolinian. Yes, it's that different. Or, put another way, most North Carolinians put into California are going to instantly hate the place. Partly because it's not as patriotic, partly because your average conversation is going to sound very aggressive.
