Can black and white be treated fairly and not buy face

I've never been mistreated like this every in my life. The girls working there are very bad at customer service, they shout us black customers and treat us poorly. I've been monitoring this for 2 Years now. Today i have proven that white and black are not treated the same, me and this lady had the same problem with our nails, i got shouted by the girl called Queen telling me shes been doing nails for 7 years while the lady was told "sorry maam i'll fix it now". i am very disgusted and annoyed. i will never go back there again.
