Absolutely ridiculous customer service. Me and my mom just got back and were usually known to get bad looks from employees (Were Puerto Rican) but today I've had it. Me and my mom were just checking out and the cashier just gave us dirty looks. Didn't say a single word to my mom and she even smiled at him and asked how his day was but he didn't even talk to her! And at the bagger, I smiled but he didn't smile back and didn't say a word. He even looked disgusted with me!!! As soon as he was done he quickly went to the next person and smiled at them (They were white) and perfectly greeted them. I've seen this happen to several costumers who were of color. Were NEVER shopping there again. DISGUSTING!
