Does this seem illegal to you?

Hi. Just picked this up from alt.dcom.telecom. Doesn't it seem like an illegal invasion of privacy to do something like this? Or maybe I just don't have the whole picture. Anyway, here it is:

GOING FROM A TO B. You're in your car. You're at A. You want to go to B. You have no idea where B is. So you go to a Sprint payphone and use its TeleMap service, give the telephone number of your destination, and receive precise directions. (Tampa Tribune 9/12/93 B&F 5) Of course, if you have a wrong phone number, that may be a problem. You may go to C, wherever that is.
