Dollar Tree

I went into the store on July 21st around 4pm. this is my neighbor store and I frequently shop in this store at least three times a week.
I had a cart full or merchandise (at least $40.00 or more). The cashier name Alisha I noticed was being very nasty to a young lady who was three people of a head of me. She was going back and forth with this young lady. Now moving forward the lady in front of me she was nice too. So now I'm next I asked her if she could separate two of the items in my bag and not bag them all together (it was spray starch). I would make it very hard for me to carry as I walk with a cane. She act like this was a problem and frowned her face up. I asked her was there a problem and she told me to not tell her how to bag. I told her why I asked her to separate the bags but that is rude and unprofessional she preceded to go back and forth with me. She then told me that I was not to tell her what to do and signed off of her register and that I could get into another line. I told her that I was not going anywhere and I asked her for her manager. She then showed me her badge and said that she was the manager. I asked her for her name and again she showed me her badge. I have never been treated in this manner at this dollar tree. As I said I frequent in here at least a couple of times a week. I feel like I was being discriminated against because the other young lady that she was arguing with was also a muslim women such as myself but the lady that she was nice to happened to be white. (she is also white). I told her that I was not going to get into another line she told me that she was not going to wait on me and proceeded to walk away. I left my cart there. I was so embarrassed and humilted and just walked out the store. I would like someone to call me in reference to this [protected] .
