To the Dairy Queen at 5001 S Crossing Pl, Sioux Falls, SD:
To the young woman with bright yellow, short, half-shaved hair, shame on you for yelling at your customers in front of our children. We understand that you were busy, but taking out your frustration on customers by yelling is not acceptable. We come to pay for a service, which in turn provides you with a paycheck. My children were in tears in the car after we left because your loud yelling frightened them. This was far from a great experience for them.
I will never visit this Dairy Queen again due to the way you treated us. You should be ashamed of yourself. Your co-workers, who were just as busy, managed to treat customers with respect, and one of them even apologized for your behavior.
You need to find a different career if you cannot handle the pressure without resorting to yelling at customers. Your attitude is detrimental to the business. Instead of yelling, consider putting up signs in restricted areas to manage the flow of customers.
