I had an oil change appointment. The representative asked permission to work on an issue that wasn't working. I agreed, but I had to ask about progress after 1 1/2 hours. They gave me a quote for repairs, but my 1 hr appointment turned into 3. I needed to return to work. Communication about realistic time frame and ongoing progress would have helped my decision to investigate the issue or not at that appointment. Yomani Williams was wonderful.
