I have a home gym now, but my old gym had separate rooms for cardio and weights. I usually do cardio outside, so there was a long time where I had never even seen the cardio room. One winter, it got dangerously cold outside, so I figured I would go check it out. There were actually fat people just sitting on the machines, machines off, eating McDonald's. I could not believe it. One was even sitting on a treadmill...
