Dollar Tree review: employee customer service

I went in to dollar tree on 12/3/19 in 30371 mount vernon road princess anne maryland around 9:00am to buy some items, when I got to the counter a black lady, kind of big, real short hair wavy, had glasses, dingy looking shirt . Reason why I gave description is because I didnt see her name tag on. She acted like she hated the world, she was slamming things into bags, told me umm do you want your receipt, umm you have to answer the screen(her own words). Her attitude is right down nasty . I said to her (umm) you have a nice day in a voice to let her know that she was rude and not a customer service person. I will goto dollar general 1 block away before I go here again. And I will be posting the incident on my facebook page to warn my friends and family about this which are many in this area and to spend your money else where . Because it seem like she has a problem with whites. It is 1:15 am and this is still bothering me .
