They didn’t go deep into the details of such usage of music, and I can’t find similar topics in the forums. So I can’t give you guaranteed 100% correct answers.
Maybe they mean by “location” that a restaurant needs just one license (?). And a license for every day doesn’t make a whole lot of sense.
Best thing to do would be contacting the Help Team. And if you’re going to do so, please let me know what they say.
