Tire Kingdom review: Wait time

I had a scheduled appointment for an oil change and tire rotation. They were taking customers who were going to spend more money. I just had tires placed on another vehicle in my household and spent quite a bit of money. I arrived for my scheduled appointment and was told they were too busy and it was going to be a 4 hour wait. If someone has an appointment, it should be honored before others are serviced. I have a busy schedule also. I also purchased tires at the same place for my own vehicle several months ago. It may be time for me to find another company that honors appointments.
