These People Have Nothing Better To Do

I saw a patron walking around the floor and mumbling Monday around 5:12pm. He approached my co-worker and said, "All of the computers on this floor are being used. As he walked away from the desk, he said while shaking his head, "THESE PEOPLE MUST HAVE NOTHING ELSE TO DO.". My co-woker said, "What did you expect, it's a Monday and almost 45 minutes before closing?"
After he walked the floor 1 more time, he approached me. He said, "I have walked all of the floors, and all of the computers are in use! These people must really have nothing else to do."
I just stared at him, until he finally walked away mumbling.

*Dude is here everyday. I don't even know why he said anything to me, because I haven't entertained him with a response any other time.
