    Our order took an extremely long time, although the young man assisting us was very polite and respectful throughout the experience. Unfortunately, our cookies never arrived. Normally, this wouldn’t have been a big deal, but we were already running short on time. We asked the young man if the cookies were still coming, and he told us they had just been put in the oven. Since we didn’t have time to wait, we asked if it would be possible to receive a refund. He went to get the manager, who came over to process the refund. Unfortunately, the manager’s behavior made an already frustrating situation much worse. She came over with a very confrontational attitude and told us that we should have simply waited. The way she spoke to me and my family was extremely disrespectful and unnecessary. I asked her to stop with the attitude, especially because my children were present, but she continued arguing and making a scene in front of them. When I asked for her name, she refused to provide it and simply walked away. I want to emphasize that the young man who initially helped us was polite and did what he could. My issue was specifically with how the manager handled the situation. A simple refund should never have turned into such an unpleasant and uncomfortable experience for my family. Based on this interaction, this is not a place I would feel comfortable returning to. 4:15 pm Mangers on staff- Hispanic Female in her late 30’s

    Never know if they are actually open because they refuse to fix their hours to reflect reality.
