Preferential treatment according to race

I LOVE seattle coffee...by far it is my fav since my first taste. However of late it has left a rather bitter taste in my soul. I often visit the Mt Edgecombe branch as it is the closest to work. Often I noted a difference in treatment of customers according to their races. I ignored this as I loved the coffee so much. When this branch reopened during lockdown I visited it and decided it would be my last. The staff treated me indifferently if a bit rudely when I made minor requests and scoffed at me but went out of their way to be friendly and courteous to their white customers. As much as I like your coffee I value my dignity far more.
