    Went through the drive thru. Everyone I encountered was professional. It seems like the burgers are about 1/2 the size they used to be

    I ordered a 20-piece nugget and 3 hamburgers with no pickle... I got my food and when I opened up my hamburgers they were cheeseburgers in the hamburger wrapper. They even had the sticker on it that said hamburger with no pickle 😞

    During a recent visit to this location, I experienced a level of service and food quality that was well below reasonable standards. Upon arrival, I was not greeted in a customary or professional manner. Instead of being asked how I could be helped or whether I would be using the mobile app, I was met with the statement, “What do you want.” I asked if I could use a code, was told yes, and then the employee went silent. I proceeded to place my order without being given a total. At the window, I explained that I had a credit from the previous month and politely asked if the employee could check the store’s log or notebook. I provided my first and last name and explained that during our last visit, an order for myself and my three children was missing items and incorrect. At that point, a manager intervened. I later learned his name was Jacob. Jacob stated, in a dismissive manner, that I would not be receiving anything and asserted that the store is “very good” about writing credits in their notebook. I calmly asked if my name could be written down and requested that the General Manager contact me. I even offered to provide my ID to verify my identity. This request was refused outright. I was told “no” repeatedly and informed that I was “not getting anything for free,” despite the fact that I was attempting to resolve a prior error, not obtain something improperly. After returning home, the food quality compounded the issue. The fries were undercooked, and the chicken nuggets were unacceptable. Out of an order of approximately 40 nuggets, several were visibly undercooked. Given that this food was for children, this is especially concerning. This experience reflects failures in basic customer service, conflict resolution, and food quality control. I am requesting that this incident be reviewed by upper management and that I be contacted by the General Manager to address both the unresolved credit from the prior visit and the issues experienced during this one.
