Dairy Queen review: customer service

Ordered food waited 15 minutes inside the store for a 4 piece chicken basket and a 6 piece chicken basket with a chocolate milkshake after the workers said they made the food and another worker took the order to another customer. Then the employees had multiple icecreams and shakes on the counter and claimed they had no idea who ordered them. I was very disappointed with the service I recieved at this location.
