The Duke of Oil at 698 East Northwest Highway, Mount Prospect, Illinois.

Horrible. I pulled up to this place a half hour ago. It was around 3:45 on a Saturday when I pulled into their driveway. I see one of the guys inside peaks through the glass overhead door and just shakes his head at me. I sat there in my car for a couple of minutes and watched guys walk around inside. They knew I was there, but nobody even bothered to open a door or come out to talk. They obviously don't need the business. Finally I just drove off. Nice customer service. I live in the neighborhood but I will never return to that place again.
