My oil change was promptly taken care of, but because of a clerical error, I was told it may be several hours. I did not have a ride, so I would need to wait.
I had called for an appointment earlier during the day, and was told about a 4:30 opening. I took the appointment, and when I showed up, there was no record of it. Somehow the appointment was listed on a different day, for a completely different time. So, I knew that it wasn't me that goofed, because a different time slot or date would not have been an option for me this weekend. I was prepared to be there for a long while, so when I was told the car was finished, and it had only been an hour wait, I was quite pleased!!
