After placing my order, I went to the portion of the coffee shop where you wait for your drinks to be made. While standing there, the woman who took my order started yelling my name, telling me to come back because my card was declined. This was quite embarrassing, considering the number of people in the line, and that she was yelling for me across the shop, when she could have come to the area where you pick up your drink and told me politely and confidentially. At this point, I was really frustrated in terms of the wait time (I was running late for work), and I was really embarrassed because she had yelled that my card was declined in front of everybody, I apologized and told her that I didn't want my order any more. She did not apologize. I will not be coming back to this location.
