I made an appointment, and showed up just a little bit early to find that it was basically a first-come, first-serve free for all. It took about 15 minutes for somebody to come up to my vehicle, and at that, the person was not qualified to check me in. Instead, the employee said that he would find the appropriate employee to assist me, and to stay put. After a little while, and with no interaction with a service tech, a porter approached me and asked if I could please move my vehicle out of the way so that other vehicles could move forward. He also instructed me to go inside to make contact with a service tech. All in all, it took 45 minutes to be attended to. Next time, I'm just showing up because I'll get attention before all the suckers who make an appointment.
