Smelly man

Sometimes there is a smelly man at the gym that wants to do the elliptical for too long. It's always too long when it's next to me. When I see him coming, I get a weird feeling in my stomach and pray he doesn't take the one next to me. And he usually does. Why? I don't know. It's awkward. When I have already committed to my elliptical to do 30 + minutes, I can't just abandon it in the middle of a workout. Then he would know that I am moving because he smells. And that's just not nice.
