"The flavors at this restaurant are top-notch, receiving a 5-star rating. However, the customer service provided by one specific manager is lacking, with a 1-star rating. Our initial visit to Churn was fantastic; I ordered the Lisa Turtle without Salty Pecans and switched the caramel sauce for peanut butter sauce, which was absolutely delicious. Unfortunately, during our most recent visit, when I tried to make the same substitution, the manager intervened and claimed they couldn't accommodate my request. Despite my insistence that they had done so in the past, she argued peanut butter sauce was no longer available, even though it was listed on the menu under the item "Pup cup." After pointing this out to her, she seemed flustered and backtracked, stating that it was actually doggy-grade peanut butter. I eventually convinced her to add the peanut butter sauce to my order, but she tried to charge me for a Pup cup instead. In addition, the manager prioritized serving two larger parties before attending to us, causing unnecessary delay. Overall, I found the manager's behavior to be unprofessional and inconvenient. I rarely write reviews, but her insistence on feedback regarding the peanut butter sauce compelled me to do so. I urge them to add peanut butter sauce to their menu for human consumption."
