    I just left the drive thru where I had the worst experience. There was a Caucasian girl that refused to give our food until we paid. When we reached for the food as I was taking my card out she snatched it away and said card. There is a nicer and correct way of saying it. I need a payment first please and then I will hand your food is how she would have said it. Very bad service and it is always the same girl that acts this way. The rest of the employees are nice.

    Customer service needs to be better. Can barely get a smile out of these workers. Absolutely no customer service. When you are ordering they rush you after every word you say. They don’t even smile and say have a good one or anything and they’ve ignored me when I say it to them. Completely rude. And I used to go there often but they made me feel like I was inconveniencing them or it’s a burden to make drinks.

    I ordered an iced pumpkin latte, and it was good, but just tasted a bit "artificial." The server was friendly and tried to help me with my app [new phone.] We used drive-through. I will return and order the same drink just to see if it does have potential for fall bliss!
