I notice so often that pretty girls get special attention from guys. They get gifts and flowers all of the time just because they are pretty.

As I a gentleman I can personally say that I treat everyone the same. Hold open doors for everyone even for people who are rude. Manners are not limited to "Pretty" girls but to everyone. If the guys around you don't have basic manners then its possibly best to find some new guy friends. As for the flowers and gifts it may be because either they are dating or the man is just trying to flirt. in my opinion0

I'm really not a fan of special treatment of random strangers because of artificial reasons like physical beauty or social class and so on. Unfortunately it does happen, but I'd say with mostly immature people. I remember seeing this phenomena a lot in high school.1
