I had a very disappointing experience today at the store

I had a very disappointing experience today at the store. I was in line to check out when another customer skipped the line, and the cashier did not intervene or acknowledge the unfairness of the situation. The cashier was also disrespectful, making a comment about how my money wasn't as valuable as the other customer's money.She said in her words that money is a duster so clearly my money isn't important because I don't have a lot of it. Wow the disrespect!! I pray that lady heals because she's bitter. The securities are, however, very friendly, and they picked up that I wasn't happy.
