Annoying gym person # 45

Then there's that guy that interrupts your workout by catching your eye because he wants to ask if you are using a certain machine that he wants to use. "You using this?" I can understand that he's just being corteous...but enough is enough. I'm always like 20 feet away from that machine so its fairly obvious I'm not using it at the moment and if I was I would probably be kinda next to it. I always reply "Nah, it's all yours..." but what I want to say is "Are you serious? I'm nowhere near that thing...seriously, I don't know why you are asking me that." But I don't because I'm a nice guy. I don't know why but I don't like my private thoughts (about how terribly out of shape I am)interrupted by sweaty people who I'm trying very hard to ignore. This is the gym after all...and it's bad enough that I pay 60 dollars a month to sit in someone else's poorly wiped sweat puddle so its just acting too much to make me interact. That's it, I'm done.
