    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.
