I am usually the last client, and my t must try to space appointments because I only occasionally see someone leaving before me, or waiting when I leave. Never the same person.

It doesn't bother me to see them or for them to see me. I am glad other people are getting help, support, whatever they're there for. Actually, I am a little curious about them because I am curious about people in general, but even then I really think it's none of my business.
