Why do women in the gym never wipe their sweat of machines after working out?

Why do women in the gym never wipe their sweat of machines after working out?
I know, it's so annoying. I find that going up to them and giving them a right good rollicking does the trick - although some of them cry and they don't wipe up after that either!
Women in my gym do either of two things -
Wipe the sweat from the cv equipment after using.
or
Come to the gym with makeup on, not a hair out of place and use the machinery in such a way as to not break into a sweat. Begging the question - why do they go. Obvious answer being to flirt and make the men look at them.......
(or am I a cynic?)
Because some woman think that they don't sweat.
because they are inconsiderate slobs.
That's being awfully generalistic. Why don't you go ask the ones that are committing the offense. While you're at it, ask the guys that don't either.
women dont sweat
Horses sweat
Men perspire
Women glow

LOL
i never see women dripping sweat off there foreheads like sweaty blokes do
Maybe it is because of the age old saying that horses sweat, men perspire and women glow. They just don't think they are sweaty enough to bother I guess.
That's like asking why men can't aim.
I always wipe after lol but not all men do so the women that aren't in your gym maybe instead of complaining ask them politely if they would also ask the men that don't too :)
