I'm not gonna say the worst can't happen to a person but living in VA my entire life and being accustomed to "southern hospitality", I have to be a bit skeptical of these situations.
No matter where you go, you'll always have at least one person saying "hey," "how's it going?," "whats up man," "good morning," etc. So if that's all it is, I have to say you're overreacting a bit. Now if it goes further than that, then you have a case.
