I found this at my work’s new location today. Ground floor of a new condo build, it’s a business if that helps. I’ve never seen plumbing not connect before, seems like an easy thing to get clogged no? Is there a logical reason for this?

Edit: Solved! An air gap (or as one user suggested, personal urinal) seems to be what it is. There are major AC units that make sense here. Thanks everyone for teaching me something new!
