Mocha Mike's

I was very disappointed!!!! I wouldn’t normally post any reviews but I was so surprised by the persons working that I felt I needed too!! I purchased coffee, gave tip and left. I took TWO sips and the coffee had an awful aftertaste. Just like milk was sour. I went back to ask for a new coffee black and waited to make sure no one else was around because I didn’t want to let other customers know. I knew this could happen anywhere no big deal. BUT the worker was so RUDE and asked me what she wanted her to do with it. I thought just toss it and give me a new cup! She did give a new cup but was not happy about it! Very very poor customer service! I won’t go back!
