You shouldn't feel bad. It sounds like you're becoming more self aware - basically getting older. Everyone treats attractive people better in all aspects of life, even if they are only slight advantages. Over time they can add up. The Freakonomics podcast just did a piece discussing attractiveness is the key attribute to get tips. It's way more important than actually doing a good job.
Also what is considered attractive is based on everyone's own perspectives and genetics.
FYI smiling at people is a sign of intelligence. I wish I still had the article to reference that though.
