Apple map problems are affecting Mac tech support

Apple map quality problems seem to be worse than Tim Cook let on: today I talked with tech support about a defective Macbook Pro Retina, and I asked the rep for the closest store to downtown San Francisco; he couldn't find it. He searched by San Francisco area code 415, and the results were on the other side of the country in New York City. He searched by San Francisco zip code 94101, and the results were in the northeast U.S. in the state of Maine. How can Apple mapping be so far off?
