The staff is always nice and helpful. However, it's my observation they are understaffed on Saturdays. Most people, including myself, work Monday through Friday and take their vehicles in on Saturday. My case in point is, I took my daughter's car in to get snow tires mounted. It was very busy, but the staff had a, "can-do," attitude. They contacted me several hours later, which was fine, and told me the car was ready. My daughter picked up the car and came back to my house. My daughter left my house in the evening. She soon called me to tell me she was experiencing a front-end shudder at 55 MPH. No doubt, in the understaffed stores effort to provide fast service, a tire was improperly, if at all balanced. Now, I will need to bring back the car. My two star rating is for management not understanding their own business model.
