Seattle coffee company worst service!!!!!!

The service sucks. A couple of months, I bought a coffee. I was standing in line ready to order and then the cashier lady served the man at the back. She greeted him politely and didn't do the same to me when I was first and she served him first, but I just left it like that. Then I went again today, different lady and she did the same thing! It seems that it's a ****** thing, every time when the whites come in then they polite once a colored comes in, no smile at all! And this is just waterfront!
