Bad Client Service

I had the most unpleasant experience ever today. I went in to shop for the 50 percent off sale when a dark skinned young lady who works at the store deliberately ignored me while she went on to happily assist other customers. At first I thought she was busy but later realized she had time for anyone but me. I'm not sure what her issue is but I refuse to take my money where I can't be given basic, decent client service. Train your employees to carry themselves in a professional manner!!!
