Things that won't map even when they're on the map

What do I do when a location or street shows up in Google Maps but I can't get a store to map to it?

Example:

I entered Hudson Booksellers at JFK Airport, in Terminal 4. The airport shows up on the map, of course, and so does the actual road the terminal is on. How do I get the store to map properly?

If anyone cared, let it be known I solved the problem. I looked it up in Google Maps and then copied how it was listed there and voilà, the stores appeared at the right place on the map. "JFK Terminal #" is how the terminals appear as street addresses, BTW. I'm sure the same is probably true of other big airports.
