None of those people at the shop I went to, just the owner and his assistant. Also, he has no waiting room, coffee service, TV to watch, and so on. And, unlike the Berkeley shops, I can hang around and watch him work should I choose to do so. As noted elsewhere, when he wanted to explain what he found that needed attention, he put the car on the lift, we both got underneath, and he pointed out what he had discovered.
It's refreshing to have such a direct connection with the guy who's doing the wrench work. However, I wouldn't mind a nice waiting room.
