How could this lady be so rude?

I work in customer service at a front desk for a spa. I’m still in college and pretty young. I basically greet people with a smile when they walk in and help them and sell packages. Sometimes I have another person at the desk next to me if it’s busy.

I just started this job and let me start off by saying I’m a woman of color. I won’t say my race but I will say that I’m not white. I’ve been told many times that I’m beautiful or pretty snd I've heard it for years now and gotten lots of compliments on my appearance. I don’t get tons of male attention but I think I’m an attractive young woman. I’m also put together.

The women who work next to me at the desk I would say are also attractive. There’s one who’s the manager who trained me and is so sweet. She’s married and I don’t think she’s a knockout but she’s attractive and is blonde and mid 20s. She’s super bubbly too. Today this middle aged white lady came in and was showing my manager graduation pics of her son.

I didn’t think too much of it at first but she went straight to her side of the desk and showed my manager how cute he looked and not me. Also when she finished her appointment I stood up to check her out and she walked right past ne to check out with my manager. The funny thing is that the lady was nice but she said how her son was graduating college and my manager asked what he was studying and the lady said finance.

Still didn’t pay attention but when the lady left my manager turned to me laughing and said how moms always try to set her up with their sons. She couldn’t stop laughing snd I was a little offended because the lady snubbed me and went right to her. I didn’t take it too personally because I’m a different race then them both but why did this happen? Lol. Even though I get called beautiful ( a lady told me yesterday) stuff like this still sucks.
