Yep. There are few fats I have seen at the gym that don't clean the machines, but I'm not going to interrupt my workout to get in a confrontation that will not solve the problem. The other one is a guy that comes in with a cut off sleeve tshirt and one of those sweat bands on his head. Looks like a tool to start with. He walks for a bit, then sets the level of the treadmill up to kill mode, holds himself up with the side hand bars and moves his feet so they just move back with the belt. Not actually running.
