Family Dollar complaint: Customer Service

On 3 separate occasion. I received poor customer service from the manager Dawn, who is a manager at the Family Dollar. I have observed her first-hand showing favoritism to her nationality when it comes to customer service. My first experience I asked for assistance, locating an item in the store and while assisting me a person walked up afterwards speaking Spanish. She didn’t ask but advised me to wait one minute while she assist that person. I thought it was poor customer service, especially for a manager, but I bushed it off. The Second incident Dawn, was ringing up my items and as she rung up the last item a Hispanic person stood in line behind me and she immediately started having a conversation with the person behind me and disregarded putting my last item into the bag. I then asked could she bag the detergent as well. She handed me the bag with a body negative body posture as in If I was interrupting her.
As she’s handing me the bag with her head turned the opposite, she also avoided eye contact. She never apologized or even said thank you, have a great day, instead she continued her conversation, leaving me to bag my item. Then I noticed as, I was walking out the door, I heard her tell the customer that she was assisting thank you a good day.
The third incident, I was next in line and there were three Hispanic people standing behind me. She looks around and walks towards the cashier, so I backed up to the second register because I saw her walking to the register and I assume she is going to ring me up because I was next, instead she bypasses the second register and uses the very last register on the end near the Hispanic people. I would have assumed she would have said, you’re next in line, you can come to this register but instead, she looks at me and proceeds to ring up all three Hispanic people that were behind me in line. Once she clears the back of the line, she looks at me and say I can take you. I advised her that it was very poor customer service and she stated you were up there what did you want me to do and she threw her hands up and walked off.

The area is predominantly Hispanic and the staff in the family dollar store appears to be ran by the majority of Hispanic, which comes off as favoritism. I would like to have this issue addressed, so that all customers are treated equally with courteous and professional customer service. This is a neighborhood store, that other races shares their money with. Please address this issue. He r name is dawn. However, im not sure if that is the correct spelling.
