Why are "snowbirds" so rude?

I moved to Miramar, FL 5 years ago. It is right above the line of where Miami/Dade county starts. My daughter and I went to the grocery store before we started unpacking. It was the first time I had ever seen to senior citizens argue over bagging groceries using cuss words, another one flipped his middle finger at someone in the parking lot. A woman ran over my 5 year old with a grocery cart and told her she should watch where she is standing! I have no idea if they were snow birds, but I will tell you the 5 years I spent there, things like that happened everyday. I think it is just the area in general. We moved to Orlando, and someone opened a door for me at the Post office, I was in shock. The cashiers at the grocery stores actually smile at you and service in general is better everywhere than in South Florida. People in south Florida in the area I lived were hateful all of the time. I hated living there.

Aww Gee. Enjoy the extra money they bring into your local economy. You must not be meeting the majority of them. I can say this because I am one of them, and I am not rude, and probably a better driver than you, too.
