South San Francisco, CA
Very fast, professional and reasonably priced. Only problem is that they do not service all makes to insure the 10 minute lube time.
There are at least two Cole Hardware (Ace Hardware) stores I know of in the city and both are staffed by friendly knowledgeable staff. They always know where I can find what I need and suggest other places in case they don't have something in stock. The only downside is that their prices do not compete with the larger wherehouse stores. But the ease of finding things and knowledgeable staff is worth the extra costs. The store near the Haight district is larger and more staffed while the one on 4th Street is a bit smaller. I would give a 5 star if it weren't for the higher prices.
