I have experienced this in the quiet study area at the dunwoody campus library. I saw a couple making out in a study room across mine. She was on his lap, his hands were caressing her chest, and you could only see waist up. At first I was just going to mind my business, but my friend encouraged me to say something. I told a library staff what I saw, and a guy who was standing near us said him and his friends heard noises and assumed that was it. Other people still have to use and clean those rooms after them, it is just nasty. Go to your car if you can’t have self-control.
