Neal: The (un)real estate agent isn't going to show you any respect not only for the reason cited above by gaucho777, but also because you're not going to be giving him repeat business. When I buy shoes, and I get friendly service, I go back and buy more shoes at the same place. It doesn't behoove the RE agent to care, because I'm unlikely to need to buy a house within his geographical area ever again.
I hate auctions where they indicate that the vintage Trek you're looking at is "like Cannondale, Bianchi, Giant" in addition to all the things mentioned above. No, it isn't, and just because of your complete lack of sophistication, I'm not going to buy it.
I really wish people would just describe what they're selling.
