I'm astounded at how many businesses give no clue about where they are located

That is a bad habit that is far from restricted to directories. I deal with it all the time on submissions to my event calendar, EVEN THOUGH I specifically list this info as "required" on the submission page.

I think the problem is that submitters think too locally, they know where they are in their community, and assume everyone else does to, because they assume they are talking to a very local audience.

But that's just a guess.
