My son made an appointment for 2:00 for a mobile mechanic to inspect his car as it would not start. Chris arrived at 1:38 while I was backing out of the driveway to pick up my son from work. He asked if he could take a look at the car while I was gone. I finally opened the garage and I explained that it wasn't my car but that my son would be home in a few minutes. He persisted to talk with me about the car and told me that he would not be able to look at it because it was not "put together completely" My son later explained to me that it would have taken 4 minutes to put the spark plugs back in, re-connect the air intake which was over the spark plugs, and put the tire back on if need be (he had the car propped up to look under it) which he planned to do before the appointment. I was late picking my son up from work. Chris cancelled the appointment at 1:53 and charged my son the $20 cancellation fee.
