    I literally just did a door dash today. I asked for a blizzard with M &M’s and sub with chocolate flavor instead of vanilla. I received what looked like chocolate ice cream with maybe 2 M&M’s!! It’s definitely not a blizzard! This was for a 4 yr old!! Good thing I had candies here to spruce it up. Someone needs to learn how to make a blizzard. Very, very disappointed!

    Normally, food from drive-thru is very good. Today, hamburger was warm and dry.

    I love DQ but this is one of the worst in the area. The kids working are nice but definitely need some help or supervision from upper management. Orders are consistently messed up or cold, the floors inside have been dangerously slippery multiple times (not just wet with water, but guests were sliding around), the soda machine is out of almost everything, and there are flies everywhere. Overall, it's a very chaotic experience and unfortunately not reliable service. I think having someone from upper management present and guiding the staff would go a long way.

    A manager named Logan very rudely shewed away an employee, with an over the top hand wave, that looked to be helping a coworker and gave him a mean look. She Doesn’t seem very professional. On top of that she angrily whispered something to the coworker the boy was trying to help. I won’t support a place with managers gone unchecked this is unprofessional and sad to see. Waste of a trip I was so upset I left without buying anything. Seeing her be rude to one employee is one thing but to two? Shows how little she cares.
