I've only come across one commercial building that actually had NM-B for the original wiring.. It was all wood construction also..
Usually I find NM-B in commercial by means of someone adding or moving wiring on their own & not knowing it's not allowed here...

PS... At least they didn't just lay it on top of the grid ceiling!
