This callout thread kinda backfired, didn't it?
I'm up there all the time, either hanging out or getting something done. Each and everytime without exception they get atleast 1 if not 10 people that are there simply to pick their brains and kick tires. Multiply that by 6 and then again by 52, and then you start to get a vague idea of how much time is wasted.
Every shop has their good days and their not so good days. I've seen personally where Arash, Sam, John, Sang, Jerel (when he was there) all stop what they were doing to attend to someone needing something seemingly small that then turns into a full blown service call. What does that do for the cars that are already UP on the rack and scheduled out? They get delayed to those customers that were there BEFORE and probably made an appointment in the first place. How's that fair? It's not.
Believe me that I've seen them do a lot for their customers. They constantly do pro-bono work whenever possible. Had your uncle come at a time when they weren't slammed, maybe they would've jacked his car up right then and there. Maybe not.
Bottomline is that he shouldn't be upset IMO. It happens and I bet that if he made an appointment and got them to figure out the problem he'd be more than happy with their service then.
