Honestly, I occasionally do this. I'm not interested in other people or interacting with them while they're running, just in walking as briefly as possible from the cardio area to the weights. Which seems silly, but in my defense, I am profoundly stupid while exercising because of anemia.
I also need a partner to keep me from repeating reps and sets. On my own, I ended up doing 800 bodyweight squats once, when I meant to do only 500. My hamstrings were pounding and my quads itched from how badly I fucked up.
