There are a few back machines where I occasionally leave the weights on (tee-bar and another row machine) though I usually put them back. I would never leave weights on any other machine -- particularly a bench press. Leaving them on the bench makes it look like someone is using it and it's annoying for everyone else.
This one guy used to put on 135, do ten 3/4 reps, go "run" 5.5mph on the treadmill for 15 minutes and then go back to the same bench and do the same thing. From what I can understand, I think he quit about 6 months ago to join the 12th street gym.
