I visited this location on July 25th, 2025 around 10 PM. I had a reward on the Marble Slab app that offered one free small ice cream at participating locations. When I entered the location, I asked an employee if they are honoring the reward and showed it to him on my phone. He looked at my app and said yes. He then made my ice cream and when I was about to check out, he excused himself to go to the back room and brought another employee to the front. I had already tapped the redeem button on the app and it was timed. The second employee apologized and said their system is down and they're unable to redeem my reward. I then tapped cancel redemption thinking I could use the reward at a different location since they were unable to process my order. But now I see the reward is no longer available in the app and today, the 26th, was the last day to redeem it. I can understand their system being down. But their employees should be familiar with the app and communicate payment/rewards issues before servicing customers. It's unfair that because the employee failed to communicate with me prior to processing my order, that I now can longer redeem my reward at any other location. read more
