Discount Tire review: winter tires

Came into the store, asked to purchase two winter tires for the rear. The cashier/ salesman wanted me to buy four tires and would not let me buy only two. He explained the safety of having four tires, and even pointed out to an Asian employee to come explain it to me, since I am Asian (I speak English well and lived here all my life). I understand the safety concerns, but just needed two tires. He would only sell me four all seasonal/ snow tires or no tires at all. Causing a scene in the store. I just left. He was very unprofressional and a disrespectful employee.
