I've never seen it open for business. The only real estate property actually advertised in the window is an old, hand-lettered sign for a home that sold for $37,000 -- most likely 50-60 years ago. Quite likely, this office has been locked shut for almost as long.
The proprietor, if he is still alive, is obviously some kind of fanatic. The shop functions as a broadcast center for his opinions: Ronald Reagan was a hero, the renaming of Army Street to "Cesar Chavez Boulevard" is something he'll never recover from, English should be the only language spoken, etc.
He's probably been tormented for decades: after all, he keeps a shop on an upscale street that features a large Aveda shop, a boulangerie, several clothing boutiques, several nice wine shops,and plenty of trendy and often useless ways to unload your disposable income.
But seriously...is this shop ever open? Who owns it?
