Absolutely, if possible. I only map this way as a last resort.

Here's one I remember doing a while back: https://www.openstreetmap.org/way/249606377

It's signed 798-812, right under the Colonel's nose. It's 798-812 on the website ( even right in the url: https://locations.kfc.com/ny/brooklyn/798-812-4th-avenue ). There's no reason to think the restrooms are 798 4th Ave and the drive-thru window is 812 4th Ave. By all available evidence, the real-world address of this place is 798-812. So that's what I tagged, and added the address interpolation way to boot. Frankly it's hideous, but I still think it's less bad than any currently-available alternatives.
