    I came with 2 toddler grandchildren which is a real experience in itself. Stressful. Lol. I really didn't want to order a drink & fries for myself but I asked for allergy info on a sandwich and I was told they didn't have it. How frustrating in today's environment on food allergies. They lady that took my order was really nice and I just came in overheated. She did go out of her way to bring me a large cup of ice.

    This was my first time using the drive-thru at this McDonald’s, and unfortunately it will also be my last. I placed my order and parked to wait for my food. Since it was my first time using the drive-thru here, I didn’t know I was supposed to pull forward to another waiting spot. Instead of politely explaining what I needed to do, the employee was extremely rude and even used profanity directly toward me. There was absolutely no reason to treat a customer that way, especially someone who was simply confused and waiting for instructions. A little patience and basic courtesy would have solved the situation. Customer service like this is completely unacceptable. I hope management addresses this issue so no one else has the same experience.

    Getting one's order wrong is the norm and should be expected at any McDonald's in 2026, however, when a customer pays extra for something and it isn't provided, that crosses the line from normal Gen Z ineptitude into actual theft.

    As a door dasher, the associate Jacob M…was utterly disrespectful. He said the order I came to pick up was not found in system. I’ve been fired as hint for 4 years, and yes that is an option within the app. I’ve never seen it happen. I asked if he could remake the order. He said my red card would not work, before even trying. Once he tried , he did so without me seeing. Afterwards, boasted about how he was right and it wouldn’t work. He proceeded to throw out slurs and disrespectful comments to me about myself and my vehicle. He also threatened to call the police on me if I didn’t leave promptly. I did not leave promptly, I contacted DoorDash support and spoke to several other members on staff regarding his actions and comments/behavior towards me . Upon speaking to other members, I discovered that no one likes him and other employees do not want to work with him as he is a disruptive character and has no business in a customer service position. Another employee, THOMAS, was apologetic for his co workers actions and proceeded to offer me whatever I wanted to for my inconvenience and disrespect received from JACOB M. I politely declined and asked why is he at the window dealing with the public. THOMAS politely responded and said it is out of his control. Great restaurant, one bad apple, we know how this goes.
