The Personal Side of Bias, Prejudice and Oppression

I can honestly say in my entire lifetime, I've never experienced bias, prejudice or oppression directly aimed at me. I'm not even sure I can think of a time when I've seen it happen to others. Actually I just thought of an experience I had the other day. I'm not sure if it's considered to be any of these three things, but I think it is because it has to do with being poor or rich. There is a local restaurant in our town and it is owned by two sisters. One of the sisters has 2 girls that I went to school with and I love them, they are super nice and the best waitresses ever. The other owner has 3 girls and to me they all 3 act really snobbish. I used to work at this restaurant in the summer time and I felt the same way. I will only eat there if one of the 2 girls I went to school with is working. So before I left that morning, I text the girl and asked if she was working. If she was working I was gonna eat breakfast there, but if she wasnt I was just going to get a sweet tea. I walked in and she wasnt working so I was just going to order a tea. So I waited a minute. The waitress (the other owners daughter) walked to a table and waited on people. Came back to the desk for a minute then fixed their drinks and another man who had ate just walks up and practically gets right in front of me and she walks up and helps him!!!!! I was SO MAD! For one, that he just got in front of me and for 2 when I was standing there it's like she didn't even notice me! I ALMOST walked out!!! I was fuming... I started getting tears in my eyes and I thought "Shanda suck it up!" Finally she looked at me and said "do you need to order some food?" I said no i just need a sweet tea. The entire time she barely looked at me. It's like she thinks she was too good to talk to me! And this was the exact reason why I wasn't eating breakfast there unless my friend was working! They've had complaints on this before, but that's the first time it has happened to me that bad. My dad is a jokester and I've been there with my parents several times and it seems like everytime we go in there my dad cracks a joke to one of them girls and they don't even laugh, they are just so not nice! Even if I go to a restaraunt where I don't know the waiters, they should be friendly! These girls are not friendly at all. So I do beleive that would be considered oppression. I feel it dimished equity by making me feel like I wasn't important and apprently she didn't need my business. Guess I wasn't dressed good enough or something. But I'm the type of person that honestly I don't care I'm not going to dress any better the next time I go in there because I dress comfortable and that's what I like. Of course then again it did hurt me because I felt like I was ignored. I mean really, I literally stood there for about 5 minutes before she asked me! To change this incident, she could have at least said, I'll be with you in just a minute or at least acknowledged me. Also, I went in there with the attitude that they were rude, maybe if I would've went in with a different attitude, then I wouldn't have even noticed (although I still would've).
