Have you ever read a real estate listing? Did you interpret a listing as any kind of guarantee as to how a prospective purchaser would get to the property without being taken there by a salesperson? I honestly never though of a listing as being an advertisement of personal services...because the sales person has access to the property (key box, etc) and the prospective purchaser does not, transportation is a given. That's why you don't see many Mini's or SmartCars in real estate agent's parking lots....more like Lexuses, Caddies, etc.
